Which of the following is NOT true about ions?

Which of the following is NOT true about ions?

Answer 1

The last one, and here’s why (pay attention):
Cations are positively-charged ions. Anions are negatively-charged ions.

What makes an atom into an ion? The gain or loss of electrons, right?

So here’s the thing: Electrons have a negative charge. Each electron has a charge of -1.

So what makes an atom gain a positive charge? It must LOSE electrons (just like in algebra, what you’re doing here is subtracting a negative).

And that’s why D is wrong. To make a cation, the atom must lose electrons. To make an anion, the atom must gain electrons.

Answer 2

D. Cations are formed by a loss of electrons.
