Element Essays

In this paper, is the basic information of the dangerous element; plutonium (Pu). Plutonium is a very fascinating element on the periodic table. It is fascinating regarding its toxic potency and involvement in weapons. Which is why I am choosing to do a paper on this element, people need to realize both how dangerous it is, what it is, how it came to be, and what it can do. Plutonium is in the transitional metals section of the periodic table. Plutonium has the atomic number 94 and a molar mass

THE ELEMENT SILICON. The element silicon was named after the latin word for hard stone or flint (silex). It is considered to be the seventh most abundant element in the universe and the second most abundant on the earth, (27.7%) after oxygen. Being a stable tetrahedral, the element is chemically considered to be highly versatile or reactive. Silicon is a tetravelant metalloid of atomic number 14, the element posses the properties of both metals and non-metals. Its chemical symbol is Si and it has

The organization of the periodic table takes account of many different factors. All elements in the table display a periodic trend. Electron configuration and properties also affect the periodic table. The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons. The periodic table depicts atomic radius by configuring them from smallest to largest as you move

Metallic chemical element chemically active, soft white color, symbol Cs, is located in the first group of the periodic table which means that he belongs to a group of alkaline elements. Atomic number 55 and atomic weight 132.905, the melting point of 28.4 degrees Celsius and a boiling point of 671 degrees Celsius and density of 1.87 g / cm 3. Cesium was discovered in 1860 by the German chemist Robert Bunsen, German physicist Gustav Kirchoff during the use of the spectroscope when they analyzed the

The element silver is one of the most fascinating elements on the periodic table. From how it was found, where it was found, and even what its uses are, this element is very interesting. Other elements are worth much more than Silver, but they weren`t one of the first five elements found. The element silver was found in river as small nuggets band also found in large cannonball that have been broken apart. When looking up who found this element it said that no one specific found the element and

Uranium is an element in the actinide series with the element symbol U. It is the 92nd element because of its atomic number of 92. This means it has 92 protons in an atom. Uranium can be found within the the crust, such as in soil, rocks, rivers, and sea water. Uranium is the 51st most abundant element in the Earth’s crust. It is about 500 times more abundant than gold. Uranium undergoes alpha decay, which produces an alpha particle. This is the least dangerous, as uranium is weakly radioactive

interesting element with 40 protons, 40 electrons, and 51 neutrons. It is the 40th element on the periodic table and has the atomic symbol Zr. Its average atomic weight is 91.224. It is found as a bluish powder or as a grayish-white metal. Zirconium was discovered as the oxide Zirconia by Martin Klaproth in 1789. Martin had been one of the first to stray away from the usual chemical analysis of the time, which included removing unknown elements and adjusting the percentages of the known elements so that

present day, where we know and continuously study the smallest molecular structure of anything and everything. It is the study of monumental things like the composition of matter itself, the chemical interactions between everything, from the purest elements to the most complex mixtures, and the adhesive components for all parts of life. Chemistry, in short, is the study of everything. There are many branches of chemistry that spread from physical, to organic, to biochemistry and they all are vital to

The chemical elements are divided into two broad groups, the metals and the non-metals. In this experiment, you will examine some members of the metal group and identify similarities and differences in their physical and chemical properties. Metals are the elements that are found in the left of the periodic table with high electrical and thermal conductivity. Metals lose electrons to create positive ion charges. Metals have a unique shine, are prone to forming, have a high tendency to form cations

Plutonium, also known as Pu, is one of the many elements that are included on the legendary Period Table of Elements. It is the chemical element that holds the atomic number 94 and is a very dense, silvery, radioactive metal that can be found in the fuel in nuclear reactors as well as in explosives for nuclear fission weapons. But, recently Gregory R. Choppin Professor of Chemistry at Florida State University, Thomas Albrecht-Schmitt, has unlocked an amazing plutonium discovery providing evidence

learning how to identify whether an object was an element, component, or a mixture and whether it was a homogeneous and heterogeneous was clarified. An element is made up of only one type of atom and no other. It is also known as pure substances.  Elements are different from compounds and mixtures since they both have two or more atoms while elements contain one of the pure elements. A material is an element if found in the Periodic Table of Elements. Sulfur, lead, tin, aluminum, copper, and helium

lanthanide elements. The first element in row 6 is lanthanum which is where the lanthanide group got its name. The word "rare” can make you think that the world is lacking these elements but the elements are in fact relatively abundant in the Earth's crust but in limited, insufficient amounts. The rare earth elements group got their name because at their initial discovery only tiny pieces of these metals could be separated from greater quantities of more common elements. rare earth elements tend to

Manganese is the 25th element on the periodic table located in period four, and group seven, making it a (transition) metal with a maximum of seven valence electrons. In a neutral atom, manganese has 25 protons, 25 electrons, and 30 neutrons. The identity of manganese is determined by having 25 protons, and the chemical symbol of Mn. It has an atomic number of 25, a mass number of 55, and an atomic mass of 54.938amu. The electron configuration of manganese is 1s2 2s2 2p6 3s2 3p6 4s2 3d5 and the abbreviated

Did you know that there are 118 elements on the periodic table? The first element appeared in the 1400’s This element was called bismuth. Since then there have been 117 other types of elements that have been discovered. Some of the elements that appear on the table are radioactive while others are not. There are many uses for all the elements on the table. However, the three most common radioactive elements that can generate energy and possible help find a cure for illnesses are uranium, plutonium

Flame Tests of the Elements Lab 1. According to your observations, which metal ion is present in your unknown samples? Explain your rationale. According to the observations recorded, the metal ion Cesium is present in the “unknown samples”. Unknown sample number five produced a violet color when placed in the flame. Unknown sample number four produced an orange color when placed in the flame. Unknown sample number one produced a violet color when placed in the flame. This evidence supports the claim

Rubidium is one of the many elements in the periodic table. It was discovered in 1861 by 2 German scientists, Robert Bunsen and Gustav Kirchoff who were using a spectrocopy to study samples of the mineral lepidolite, while they were studying this mineral they noticed deep red spectral line that they had never seen before, eventually Bunsen isolated the element of Rubidium Metal and it was official that he had found a new element. Rubidium is actually used as an element in fireworks to give them a

These things are called elements and each have different and similar properties. If you keep breaking up those elements until they can’t be cut anymore

Calcium is an element in the human body. It was discovered in 1808 by Humphry Davy. Humphry Davy was a chemist and an inventor. Calcium is a chemical on the Periodic Table with the symbol Ca and atomic number 20. Calcium is a soft gray alkaline earth metal, it is the fifth-most-abundant element by mass in the Earth 's crust. The element calcium ion is also the fifth-most-abundant dissolved ion in seawater. Free calcium metal is too reactive to occur in nature or it is natural. Calcium is produced

There are 117 scientific elements of the periodic table. Each have their own very distinct identities. They were all discovered by different people, at different times, and in different locations. Each element also has specific properties that only identify that particular element. They all have their own specific uses, but some can be combined to make for a stronger alloy or mixture. Silver is no different from every other element in its uniqueness. The element of silver was discovered and named

Typically atomic radius increases as the elements go down a family. As the elements go down a family, they generally have an increasing number of energy levels or shells which results in an increased distance from the nucleus which makes the atom larger. Since the energy level is increasing, the screening level also increases. This means that the electrons are blocked and are held more loosely than other electrons closer to the nucleus. This causes the atom to be larger. As atoms go down a family
