Electron Configuration

Question 1

What letter order do the “houses”, or orbital shapes go in?

Answer 1

S, P, D, F

Question 2

How many electrons can fit in one orbital?

Answer 2

two

Question 3

What is Pauli’s exclusion principle?

Answer 3

each orbital can hold a maximum of two electrons with opposite spins

Question 4

What is Haund’s rule?

Answer 4

Within a sub level, place one electron per orbital before pairing them. (don’t share a room unless you have to)

Question 5

What is Aufbau’s Principle?

Answer 5

Electrons fill the lowest energy orbitals first (lazy tenant rule)

Question 6

What is the Valence shell?

Answer 6

the outermost quantum level in an atom (highest number in electron configuration)

Question 7

How do you count Valence electrons?

Answer 7

Add the exponents in all the quantum levels in the valence shell. (ONLY FOR S AND P)

Question 8

How does Lewis Dot Structure work?

Answer 8

Show each valence electron as a dot around chemical symbol (maximum two dots per side, no more than 8)

Question 9

What does ‘n’ represent?

Answer 9

The quantum level

Question 10

shape of ‘S’ orbital

Answer 10

round

Question 11

shape of ‘P’ orbital

Answer 11

lobed
