What is the Law of Conservation of Mass?
In a chemical reaction, matter is neither created nor destroyed
What are Reactants?
The starting substances that react in a chemical reaction.
What are products?
The new substances that are created in a chemical reaction
What kind of electrons are involved in bonding?
Valence Electrons
What is a Cation?
Positively charged Ion
What is an anion?
A negatively charged ion
What is a chemical formula?
A representation that shows what elements a compound contains and the exact number of the atoms of each element in a compound
What group of elements do all atoms try to mimic when bondng?
Noble Gasses
What is an Oxidation State?
Natural charge of an atom of an element
What is an Ion?
An atom or molecule with a net electric charge.
What is a chemical subscript?
Small sized number on the bottom right of any chemical symbol used to balance a chemical formula.
What rule to all atoms try to follow when bonding?
Octet rule, all atoms try to get to 8 valence electrons
What is an Ionic Bond?
Bond between a metal and a nonmetal
What is a Covalent Bond?
Bond between two nonmetals
What is a chemical coefficient?
Large sized number placed in front of a whole chemical formulas used to balance the entire chemical reaction.
What is the most common type of bonding on Earth and why?
Covalent, mostly because water is a covalent bonding compound and is the most common substance on earth.
What is a Molecule?
Discrete units formed from Covalent Bonding
What is a Nonpolar Bond?
Covalent bond in which electrons are shared equally by both atoms
What is a Polar bond?
Covalent bond in which electrons are not shared equally which results in one end being slightly positive and one end being slightly negative.
What does it mean that compounds have fixed ratios when they are formed?
Each compound has its own unique formula.
Example: H2O is always water but the moment you add another atom such as oxygen (H2O2), you change the compound into something else entirely.
