atomic

Question 1

how many e- appear in n=2, and do they occupy the same space

Answer 1

yes they occupy the same space, 8 e- are in the second orbital rings.

Question 2

what do the amount of n equal to?

Answer 2

the # of n gives info of the size (amount of rings)

Question 3

n value =?

Answer 3

size and energy of orbital

Question 4

what does the first orbital ring have?

Answer 4

the e- in the first orbital has lower potential energy

Question 5

all e- in the same shell have what kind of energy?

Answer 5

same energy

Question 6

what is spin?

Answer 6

each orbital can have 2 e-, they both will spin in opposite directions (up or down)
- most of the time they come in pairs

Question 7

what is aufbau’s principle?

Answer 7

e- must fill orbitals with the lowest energy first

Question 8

what is hund’s rule?

Answer 8

single electrons will fill up the orbitals, then pair up

Question 9

what is pauli exclusion?

Answer 9

2 e- within the same orbital MUST have opposite spins

Question 10

how does an atom become an ion?

Answer 10

atoms will lose or gain e- to either empty a sub shell or gain an electron

Question 11

how does an atom become an ion?

Answer 11

atoms will lose or gain e- to either empty a sub shell or gain an electron

Question 12

what’s the rules for losing e-?

Answer 12

-highest energy subshell is emptied first
- once filled, 3d subshell becomes smaller (more stable) than 4s subshell
- 4s e- will e lost before 3d (due to the formation)
