atomic structure

Question 1

what is an energy level?

Answer 1

electrons are located at distinct energy levels at different distances from the nucleus.
- 7 different energy levels

Question 2

what are the 4 sublevels and their respective orbitals and electrons

Answer 2

s - 1 orbital - 2 electrons
p -3 orbitals - 6 electrons
d - 5 orbitals - 10 electrons
f - 7orbitals - 14 electrons

Question 3

AUFBAU principle

Answer 3

electrons fill available orbitals ground state up, all electrons must be lowest possible.

Question 4

HUND’s rule

Answer 4

electrons fill orbitals so that no pairs are put into orbitals unless necessary.

Question 5

Pauli exclusion principle

Answer 5

electrons can either spin up or down

Question 6

Heisenberg uncertainty principle

Answer 6

one cannot determine both the position and momentum of an electron.
