Columns of elements

Question 6

Ground state

Answer 6

Lowest -energy level

Question 7

Degenerate

Answer 7

Systems of equal energy

Question 8

Paramagnetic

Answer 8

Magnetism because electron counts aren’t full

Question 9

Order of stability

Answer 9

Full / half / any thing else

Question 10

Answer 10

Atomic # - core elections

Question 11

What trends does atomic radius have

Answer 11

As you move down left it increases

Question 12

Answer 14

Full charge of protons

Question 15

How to determine metal atomic radius

Answer 15

Half distance between elements next to eachother

Question 16

How to determine non metal atomic radios

Answer 16

Half distance between two atoms banded together

Question 17

Atoms without unpaired electrons react how to magnets

Answer 17

Repelled

Question 18

Ionization energy

Answer 18

Energy required to remove election

Question 19

Ionization energy trends

Answer 19

Up right because when there is full orbital it is harder to remove electron and when atom is smaller it is harder to removd

upper right is biggest negative

Question 22

Metallic trends

Answer 22

Down left

Question 23

where do you pull electrons from

Answer 23

highest energy level

Question 24

weird rows for electron configs

Answer 24

copper and chromium

Question 25

why are copper and chromium weird

Answer 25

they fill 3d before 4s

Question 26

what were results of rutherfords experiment

Answer 26

most alpha particles passed through suggesting atom is mostly open space
a few alpha particles were reflected by gold foil suggesting they hit the positive center
some alpha particles were scattered by the gold foil suggesting the presence of a concentrated positive center in the atom

Question 27

how does emission spectra work

Answer 27

electrons relax from certain energy levels to certain lower ones
