What does Hund's Rule tell us

1 electron per orbit first before it'll hold 2.

What is the best way to describe a 'Bohr diagram'?

Electrons in fixed orbits around a nucleus

What is a 'sublevel'?

The orbitals that are found within an Energy Level

The Aufbau principle states:

Electrons occupy orbits of the lowest energy first

Pauli's Exclusion tell us that

Orbits can hold, at most, 2 electrons with opposite spins

As you look down a group on the Periodic Table, what happens to the # of energy levels?
The increase
The stay the same
It depends
They decrease
7
What does Hund's Rule tell us
Aufbau and Pauli should.... (use your imagination)
Electrons will occupy lower energy levels first
1 electron per orbit first before it'll hold 2.
Electrons can pair up within orbits
8
What is the best way to describe a 'Bohr diagram'?
A large nucleus with electrons stuck in it
A nucleus with 3-D clouds drawn around it
Electrons in fixed orbits around a nucleus
Electrons with variable orbits around a nucleus
9
What is a 'sublevel'?
The level you need to get on
The level electrons fall to when they lose energy

The Aufbau principle states:
Electrons occupy orbits of the lowest energy first
Mr. Schultz is a chemistry prodigy and is always right (ha)
An orbit can only hold at most, 2 electrons
Electrons will all have the same 'spin'
13
Pauli's Exclusion tell us that
Pauli must be sent to a desert island
Orbits can hold, at most, 2 electrons with opposite spins
Electrons must 'spin' in the same direction
Electrons will occupy the lowest energy level first
