Electrons

Quanta Definition

• The minimum amount of energy that can be lost or gained by an atom

Electron Configuration Definition

• This indicates the filling order of all the electrons in an atom

Energy Levels

• Region where most electrons will be found

• When electrons are closer to the nucleus = lower energy levels

• Farther from the nucleus = higher energy levels

What is Aufbau Principle?

Electrons will fill lower levels before filling the higher ones.

What are the sublevels?

s, p, d, f

Valance Electrons Definition

• The outermost electrons

  • This doesn’t only have to be in the outermost shell

Electron dot diagram definition

• Shows the number of s and p valance electrons there are

What is Hund’s Rule?

• Orbitals of equal energy are each occupied by one electron first

What is Pauli’s Exclusion Principle?

• Within an atom, no two electrons can have the exact same set of 4 numbers
