Atomic and Ionic radii

Question 1

which is larger, anion or parent ion

Answer 1

anion

Question 2

which is larger, cation or parent ion

Answer 2

parent ion

Question 3

which is bigger, cation or anion

Answer 3

anion

Question 4

what is the charge of an anion

Answer 4

anion is negatively charged, it is gaining electrons

Question 5

what is the charge of a cation

Answer 5

cation is positively charged, it is loosing electrons

Question 6

as you go to the right of periodic table, what happens to atomic radius

Answer 6

it decreases

Question 7

as you go down periodic table, what happens to atomic radius

Answer 7

it increases

Question 8

how to calculate Zeff

Answer 8

Zeff = atomic # - #of shielding electrons (Zeff - Z - S)

Question 9

What is Z in Zeff formula

Answer 9

nuclear charge

Question 10

what is S in Zeff formula

Answer 10

of electrons in lower energy levels (all the other electrons that aren’t valence)

Question 11

as atomic radius increases, what does Zeff do

Answer 11

Zeff decreases

Question 12

what relationship does Zeff and atomic radius have

Answer 12

an inverse relationship

Question 13

as atomic radius decreases, what does Zeff do

Answer 13

Zeff increases
