What ion is form when an atom gains electrons?

Answer 1

Typically, a negative ion is formed by gaining electrons. This is because electrons hvae a negative charge. An example of a case where a positive ion can be formed by gaining an electron is when an ion with a charge of +2 can gain 1 electron and become +1. Technically in this case, a positive ion was formed when an electron was gained but the trend was that the ion became more negative not positive.

Answer 2

When you say a positive ion, I assume you mean, for example, Fe2+ which means that the atom has lost 2 electrons. The basic rule is: Metals like to lose electrons (and therefore become positive ions, or cations as they are called) and non-metals like to gain electrons (therefore becoming negative ions, or anions).

The way I remember this is:

Onions are bad ----> Anions are negative e.g. Cl-
Cats are good ----> Cations are positive e.g. Ag+

Answer 3

A atom that has gained a electron is a negative ion because electrons are negative and protons are positive. Before the atom was balanced and equal but now there is more negative power if you get what i mean. Hope I helped =D

Answer 4

An atom forms a negatively charged ion, known as an anion, when it gains electrons. This occurs because the addition of electrons increases the negative charge of the atom, resulting in a net negative charge for the ion.

Answer 5

When an atom gains electrons, the ion becomes a negatively charged ion.

Answer 6

lost electrons. i remember it by :

-im about to lose an electron

-are you sure?

-im positive!

Answer 7

An anion, or negative ion is formed when an element gains electrons.

Answer 8

If an element gains an electron or electrons it will become a negative ion (anion). This makes sense because electrons carry a negative charge.

Answer 9

an ion gains or loses electrons
