Me with these two chemistry questions, image attached.

Explanation:

15

The most common form of an ion ends at ate. So the nitrogen ion is nitrate because NO3 is its most common form.

Sodium is an ion that gives away an electron

Nitrates are more than happy to receive the electron.

The correct answer is Sodium Nitrate. The answer is B.

Cations are positively charged (Cu+2). These give away electrons.

Anions are minus entities. they receive  electrons. ide is a single element that receives the electron. The question is intended to trick you. Though not needed for the this equation, the anion should have a roman numeral.

A is the most correct, but it is not (I don't think) the intended answer. I would hold my nose and choose B.
