repel

Question 14

Most trends follow an arrow on the periodic table going from

Answer 14

Lower left to upper right

Question 15

Properties that are higher on the lower left

Answer 15

Metallicness, radius

Question 16

Shielding

Answer 16

The repelling of electrons away from the nucleus in ascending groups

Question 17

Effective Nuclear Charge (ENC)

Answer 17

Attraction of protons in the nucleus to electrons, considering weakened attractions by shielding

Question 18

ENC formula

Answer 18

of protons - # of shielding inner-shell electrons

Question 19

Moving right in the same period does what to ENC and radius?

Answer 19

More ENC, less size

Question 20

Paramagnetism or Diamagnetism would be based off what electron subshell?

Answer 20

The last that came in the electron configuration, NOT the highest shell
