Question

The charge on cations------ down a group

a. remains constant
b. does not have a fixed pattern
c. increases
d. decreases

Answer 1

is K as a cation and Li both +1?

Answer 2

i dont understand you @aaronq which one is the right option

Answer 3

i know when i wrote that i thought i was confusing too.

Elements want to achieve an octet (8 valence electrons), in order to do that they lose or gain electrons.

for example Li loses one electron to become a 1+ cation
Na also loses 1 electron and become 1+ cation

both are in group 1

similarly for group 2
Mg becomes a 2+ cation and Ca become a 2+ cation..


see the pattern?
