1
Q
Standard States of the Elements
A
Solid, Liquid, Gas
2
Q
Empirical Formula
A
simplest formula of a compound found by dividing all the subscript numbers by a common factor.
3
Q
Molecular Formula
A
specifies the number of each atom type in a molecule. Can be determined by molecular structure
4
Q
Ionic Bonding
A
ions of opposite charges bond. Energy is lowered because of the electrostatic attraction between cations and anions
5
Q
Covalent bonding
A
electron pairs are shared between atoms. energy is lowered as a result of electrostatic attraction to the bonded nuclei
6
Q
Octet Rule
A
In order to achieve 8 e- in their valence shell, atom bond to achieve spherical electron densities. This may lower the electrostatic energy
