@Liv1234 What do you think the answer is?

Answer 4

I think it's A, but I don't think I'm right.

Answer 5

that's not it. are you familiar with what an ionic bond is?

Answer 6

Sort of.

Answer 7

Let me explain

Answer 8

An ionic bond occurs between a metal and a non metal

The metal transfers its electrons to the non-metal.

metals generally like to lose electrons and because of this they have low electronegativites

Non metals like to gain electrons because they have a higher electronegatvity.

But the reason for this is that non metals like to gain electrons because they can satisfy octet in doing so. Same for non metals.

make sense so far?

Answer 9

Yes, it does make sense, so would the answer be C? Because potassium is a metal and iodine is a non-metal?

Answer 10

Yes that's the answer but let me show you what's going on there.
