New cards
Bonding electron
An electron that is bonded to the central atom.
2
New cards
Lone pair
Electrons that are not shared or bonded, often represented as small pairs around the central atom.
3
New cards
Ionic bond
A type of bond where atoms steal electrons from one another.
4
New cards
Covalent bond
A bond where electrons are shared between atoms.
5
New cards
Polar covalent bond
A type of covalent bond where electrons are unequally shared between atoms.
6
New cards
Criss cross method

A technique used to predict formulas of compounds based on family charges. (Criss cross the charges for the element number)

7
New cards
Electronegativity
The ability of an atom to attract electrons within a bond.
8
New cards
VSEPR geometry
The predicted shape of molecules based on the Lewis structure.
9
New cards
Ionization energy
The energy required to remove an electron from an atom.
10
New cards
Isoelectronic ions
Ions that have the same number of electrons; the one with greater positive charge will be smaller.
11
New cards
Resonance
The concept that a molecule can be represented by multiple valid Lewis structures.
