Which of the following elements would have the largest third ionization energy: K, Ca, Ga?

Question

What is third?

Thanks in advance.

Answer 1

Third ionization means the third electron has been pulled off.

Answer 2

Hm, so would the answer be Ga, since it is on the right side of the periodic table. Ga's nuclear charge would be greater

Answer 3

Go to www.webelements.com, click on the elements, scroll down the right side of the page to electronic properties, click on that which will go to the ionization section. First, second, etc are given.

Answer 4

Nevermind, I got it :) Thanks!
It's calcium because the third electron would be the full shell, 3p6.

Answer 5

right

Answer 6

name the most suitable way of separating oil from simsim seeds?

Answer 7

I don't know what a simsim seed is and neither does Google.com. In the future, don't piggy back on another post for a separate post but go to the "post a new question" and click on it.
