This is a visual representation of the valence electrons of an atom, ion, or compound.
What is a Lewis Dot Structure?
100
This type of compound is made by combining a monoatomic metal cation with a monoatomic nonmetal anion.
What is a Binary Ionic Compound?
100
This type of compound is composed of three or more elements.
What is a Ternary Ionic Compound?
100
This is the name of the system that uses roman numerals to denote the charge of a cation.
What is the Stock System?
200
This type of ion is formed when a metal loses one or more electrons.
What is a cation?
200
The Lewis Dot Structure for this element is represented by an "S" surrounded by 6 dots. (2 dots at 12:00; 2 dots at 3:00; 1 dot at 6:00 and 1 dot at 9:00)

When writing chemical formulas, the overall charge of ionic compounds must be this.
What is electrically neutral?
300
This type of ion is formed when a nonmetal gains one or more electrons.
What is an anion?
300
Superscripts and brackets are used to represent these when drawing Lewis Dot Structures.
What are ions?

V(OH)₅
What is the chemical formula for Vanadium (V) hydroxide?
300
These are used when more than one polyatomic ion is present in a chemical formula.
What are parentheses and subscripts?
400
When atoms combine to form molecules, they generally lose, gain, or share valence electrons until they attain this magic number.
What is 8? .... (referred to the octet rule!)
