Important terms
1: Proton
Positive charged atom
2: Neutron
Neutral charged atom
3: Electrons
Negative charged atom
4: Nucleus center part of the atom (with protons and neutrons)
5: Electron shell
The valence area where the electrons are located
6: Electromagnetic force
One of the four fundamental forces that changes electrons to nucleus
7: Photon
Basic Unit of light
8: Ion
Atom that lost or gained an electron. Which becomes either negatively or positively charged
Atoms
Atoms contains a nucleus at it’s center. The nucleus contains positively charged protons and neutrally charged neutrons. Electrons are the negative charge and bound to the nucleus by the electromagnetic force.
Electrons
Electrons orbit around the …show more content…

Each pair has an opposite spin (cancels the magnetic influence and creates magnetic neutrality).
Valency and Valence Electrons
Outermost shell is called its valence shell. Valence shell has the strongest energy and the most reactive. Inner shell don’t participate in chemical bonding and reactions (usually). Valence electrons can be gained/lost/shared to form chemical bonding (from this reason elements with same number of valence electrons tend to have similar chemical property).
Since they gain/lose/share the same way.
Free Electrons
Valence shell electrons have the weakest attraction since they are the furthest to the nucleus. When the electrons are loosely bonded thy start to randomly wandering around (free electrons). This happens the movement is controlled by the electronic current.

Molecular Bonding
Electrons are responsible for chemical bonding. Sharing electrons between atoms to make molecules (bonding, covalent, and ionized).
Covalent bonding: sharing the valency electrons (usually only one electron on the valence shell).
Ionic bonding: Atom uses on electron to the other. The first stom become positively charged and the second becomes negatively charged. This creates an attraction between the two

Covalent bonding - Covalent bonding is when two atoms share electrons this can only occur between two non-metals. They share electrons to fill up their outer shells, this makes the atoms stable. A Covalent bond can form up to one to three Covalent bonds with non-metals depending on how much electrons they possess. They don't always share electrons

Matter is made up of atoms; atoms are made of positively charged protons, neutral neutrons, and negatively charged electrons. 3. The measure of space that the molecules occupy (volume) is derived from the space in between the molecules and not the space the molecules contain themselves. 4.

Explain Why Covalent Is The Best Naming System

bound much tighter and form more stable molecules than atoms of the ionic bond. The chemical formulas for covalent compounds are referred to as as molecular formulas because they exist as separate molecules. Another reason on why covalent is the best naming system is because the things in our daily lives such as oxygen, nitrogen gas, water vapor, and carbon dioxide are all made up of covalent compounds. Covalent compounds are common in the air we breathe, the gas we use to fuel our cars, the water we drink and even the food we eat. Without this bond we wouldn't have the things that help us carry on with our lives.

COVALENT chemical bonding is the process in which two atoms share a pair of valence electrons. As the binary opposite to ionic bonding, covalent bonding processes lead to stable molecules once they share electrons in a particular method to create a noble gas configuration for each atom. (HyperPhysics,2014) Using hydrogen as an example which forms the simplest covalent bond, two hydrogen atoms contain one valence electron each where in the structure of an atom the 1st shell contains two electrons. The two hydrogen molecules contain one valence electron each and once paired together in a covalent bonding process form a single atomic atom.

Democritus: The Most Influential Ancient Greek Philosophies

An atom by definition as said by Webster dictionary is “The smallest particle of a substance that can exist by itself or be combined with other atoms to form a molecule.” Before we had any of this knowledge, many of philosophers and many of scientists worked on the idea of atom. One of the earliest philosopher that studied Atoms was Democritus. Democritus was very influential Ancient Greek philosopher. He was the one who created the Atomic Theory, but he didn’t create it himself, it was his mentor’s idea, which he made famous.

Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
