REVIEW DAY 2

According to the Aufbau Principle, what should happen before filling a higher energy orbital?

• The higher energy orbital should be filled first

• The lower energy orbital should be filled first

• Both orbitals should be filled simultaneously

• The order doesn't matter

What is the maximum number of electrons that a p orbital can hold?

• 2 electrons

• 6 electrons

• 10 electrons

• 14 electrons

The Pauli Exclusion Principle states that:

• All electrons must spin in the same direction

• Electrons must fill higher energy levels first

• No two electrons can have the same set of quantum numbers

• Electrons must always be paired

In an orbital diagram, what does an arrow represent?

• A neutron

• A proton

• An electron and its spin

• An empty orbital

What is the correct order of orbital energy levels from lowest to highest?

• f, d, p, s

• s, p, d, f

• p, s, d, f

• d, f, p, s

How many electrons can an s orbital hold at maximum?

• 2 electrons

• 6 electrons

• 10 electrons

• 14 electrons

For the element Potassium (K), what is the atomic number?

• 39

• 20

• 19

• 18

Hund's Rule is similar to:

• Finding a seat in a movie theater

• Finding a seat on a bus

• Finding a seat in a classroom

• Finding a seat at home

The word 'Aufbau' comes from which language and means:

• Latin, 'to arrange'

• Greek, 'to build up'

• German, 'to build up'

• French, 'to organize'

In an orbital diagram, what does a box represent?
