Chemistry

Question 1

What does the Principal quantum number inform?

Answer 1

energy levels

Question 2

what does the orbital angular momentum quantum numbers inform?

Answer 2

sub-levels

Question 3

what do magnetic quantum numbers inform?

Answer 3

orbitals

Question 4

what do electron spin quantum numbers inform?

Answer 4

electrons

Question 5

What is the Heisenberg uncertainty principle?

Answer 5

you can never be certain of two properties (speed/direction) at the same time

Question 6

what is aufbaus principle?

Answer 6

electrons fill orbitals starting at the lowest available energy states before filling higher states

Question 7

What is the Pauli-exclusion principle?

Answer 7

two or more identical particles w a half-integer spin cant occupy the same quantum state within a quantum system simultaneously

Question 8

What is Hunds rule?

Answer 8

every orbital in a subshell is singly occupied with one electron before any one orbital is twice occupied; all electrons in singly occupied orbitals have the same spin

Question 9

The dot diagram

Answer 9

The little numbers above each column ( not counting the ‘d’ level) are how many dots go on the element in specified column. where 13 is, is actually ‘3’
