200
Cations and Anions
What are negative or positive ions called?
200
The meaning that bonds in which the bonded atoms have an unequal attraction for the shared electrons.
A chemical compund whose simplest units are molecules.
What is a molecular compound?
300
Refers to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure.
What is Resonance?
300
Determines the length of each period in the periodic table.
What does the number of electrons that can occupy sublevels that are being filled determine?
300
Molecules
Electron dot notation can also be used to represent what?
400
A measure of the ability of an atom in a chemical compound to attract electrons.
What is electrongravity?
400
Chemical compunds tend to form so that each atom, by gaining, losing, or sharing electrons has an octet of electrons in its highest occupied energy level.
What is the octet rule?
400
Covalent, chemical ionic.
What are the three major types of bonding?
400
Uncompletely filled main energy levels.
Where are valence electrons located?
400
Number of electrons

Which atom is usually the central atom when drawing Lewis structures?
500
S-Block, D-Block, P-Block, F-Block.
What are the groups located within each of the four block areas?
500
A multiple bond is needed when there are not enough valence electrons to complete octets by adding unshared pairs.
In writing Lewis Structures, how is the need for multiple bonds generally determined?
