VESPR

This theory states that pairs of electrons spread out to minimize repulsions. This theory is used to predict molecular geometry.

Shared Pair

2 electrons used to form a bond between atoms

Lone Pair

2 electrons on an atom that are not being shared; takes up more space than a shared pair

Single Bond

A bond made of 1 shared pair

Double Bond

A bond made of 2 shared pairs

Triple Bond

A bond made of 3 shared pairs

Octet Rule

Nonmetal atoms will share electrons so that they have 8 electrons in their outer shell (to have a more stable electron configuration)

Expanded Octet

atoms that can have more than an octet because they house the additional electrons in their d-orbitals; only elements in period 3 and below on periodic table can form this
