P1 - Volumetric Analysis Made Easy
The periodic table is split into 8 different categories. Group 1 consists of alkali metals which are very reactive. However group 7 contains very reactive non-metals. The periodic table starts from alkali and ends at noble gases (Group 8). Sodium (Na) and Potassium (K) are examples of alkali metals. Helium (He) and Krypton (Kr) are examples of noble gases. The elements that fall under the same groups have similar chemical properties. Atoms of the elements in group 1 all have one electron in their most occupied energy level also known as the outer shell. In group 1, as you go down the list, the elements get more reactive due to the fact that the outer electron is far away from the nucleus. As you go down the …show more content…

Periodicity also refers to the recurring patterns that are seen in the element properties. Dmitri Ivanovich Mendeleev arranged the elements in order of increasing mass. Based on the properties that were displayed by the known elements, Mendeleev was able to take an estimate of where the missing places were in his table. These were also elements yet to be discovered.
In the periodic table, each element has its own atomic mass and number. Atomic mass is the total amount of protons and neutrons in an element, atomic mass is usually larger than the atomic number. Atomic number means how many protons the element contains. All atoms of a particular element have the same atomic …show more content…

The bond is usually between a metal and a non-metal element. Atoms in a covalent bond are held together by electrostatic forces of attraction between a positively charged nuclei and negatively charged shared electrons. Every atom has a different structure or shape. The shape of an atom can change depending on the number electrons. A tetrahedral atom is in a pyramidal structure. This is because of the lone and bonded pairs of electrons. The lone pairs push the bonded pairs away, this is why they

4.) I noticed that there is a relationship between the ionic radius and the atomic number of the representative elements in Group 1A. The higher the atomic number, the bigger the ionic radius is. So, while hydrogen has an atomic number of 1 and Francium has an atomic number of 87, it is safe to assume that FR has a higher ionic radius. This is true; the ionic radius for Hydrogen is 0.012, and for Francium, it is 0.194.

Task 1 (P1) The periodic table is laid out into groups and periods. They are also put into different blocks S-Block, D-Block, P-block and F-Block due to their energy levels. They are organised by their energy levels and chemicals properties. As the elements go along the periods in the periodic table the electronegativity increases but as the elements go down the groups the electronegativity decreases.

Each supernatural, equine Periodic is described differently and no two are described the same way. Each Periodic is different just like each element of the periodic table is unique. Isdell uses physical characteristics of individual elements, such as color, mass and weight, as well as chemical characteristics of individual elements, such as boiling point and melting point, to describe the corresponding Periodic in the book. As Julie journeys through the Elemental Forest, she meets groups of Periodics. Typically these are Periodics that represent groups of elements that are similar but not the same.

Atoms are made up of three basic components: Protons, Neutrons, and Electrons. The proton particle carries a positive charge while the neutrons carry no charge(neutral). When combined, the protons and neutrons make up the central part of the atom also known as the nucleus. The electrons carry a negative charge and its role is to circle around the nucleus. Each atom also has a unique number of both protons and neutrons that is known as the atomic number.

Where as, electrons are negatively charged(Doc.3).The neutron is the dense middle of the atom(Doc.3). The protons and neutrons in the atom are in the nucleus(Doc.3). However, the electrons preside in electron clouds outside the nucleus(Doc.3). To sum up, an atom is a small structure that defines what an element is and

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, and combine with oxygen to give mostly basic oxides.

Atom of an element is made up of three different components; protons, neutrons, and electrons. As we know the protons of an element will not differ from atom to atom, and electrons can move around when undergoing chemical change. However, the number of neutrons, of the same element, can vary from atom to atom. Atoms of the same element, with the same number of protons but with different number are neutrons

The ionization energy for the transition metals however are not as consistent and form little bumps on the graph The elements Beryllium, Boron, Magnesium, Aluminum, Zinc and Gallium form little peaks and troughs for both the atomic radius and the ionization energy The elements that are found on the peaks of the AR graph are the elements Hydrogen, Lithium, Sodium and Potassium. These elements are better known as the Alkali metals and are found in the far left column of the periodic table, also known as group 1. The elements that are found on the troughs of the AR graph are the elements Helium, Neon, Argon and Krypton. These elements are better known as the noble gases and are found in the far right column of the periodic table, also known as group

Particles are labeled in many ways. One way particles are referred to be as atoms (elements). They’re identified by their properties, number or protons and neutrons and atomic number. Another way particles are referred are as molecules (covalently bonded- nonmetal to nonmetal). For example, water is a molecule because it’s composed of nonmetals.

Halogens are group 17. Halogens are highly reactive in elemental form. Even though this group only needs one electron in its outer level, it has seven electrons. When halogens are in gas form they are diatomic molecules. Diatomic molecules are two atoms in the same covalent bonds.
