Question 13

Why do metals donate electrons

Answer 13

To gain an empty outer shell to form positive ions

Question 14

Why do non metals always accept electrons

Answer 14

To get a FULL OUTER SHELL they form negative ions

Question 15

What is a group 1 called

Answer 15

Alkali metals

Question 16

What happens when you go down Group 1

Answer 16

Gets more reactive

Question 17

Why does it get more reactive when you go down Group 1

Answer 17

As the outer electron is further from the nucleus so donated more readily (the force of attraction is less)
