Answer 1

1: Group B elements are reffered to as 'Transition metals' they either lose or gain electron.
2:Group VIIA elements are the halogens and form ions with charges of -1 as they gain one electron.
3:polyatomic ion, the -ate ending indicates one less oxygen than the -ite ending.
4:O2- is anion.
Mg2+= cation
Al3+=cation

Answer 2

@Ryaan for number one the answer choices are A. share

B. cannot be determined

C. gain

D. lose

so I'm a bit confused when you say that they either lose/gain electrons.

Answer 3

I mixed up something when I said that sorry !

That would be ''C'' they lose electron when they form ions/cations.
But they lose 2 or 3 electrons (Transition metals)Group B. example iron etc!

Answer 4

it's okay, I appreciate it lol
