Q

Do group 1 and 2 elements gain of lose electrons?

A

They lose electrons to form positive ions

17
Q

What elements are group 1 and 2?

A

Metals

18
Q

What elements are group 6 and 7?

A

Non metals

19
Q

Do groups 6 and 7 gain or lose electrons?

A

They gain electrons to form negative ions

20
Q

Who can form ionic compounds?

A

Only elements at opposite ends of the periodic table

21
Q

What is the overall charge of an ionic compound?

A

Zero

Negative charges balance out the positive charges
