An atom that gains or loses electrons becomes?

Answer 1

Electrons have a negative charge, so they are usually written as "e-". When an atom loses an electron, the net charge on the atom increases.

Suppose a hydrogen atom is hanging out (note that hydrogen is diatomic, but ignore that part for now) and somehow loses its electron. The electron will get taken up by something else with a positive charge (opposite charges attract each other). In general it would look something like the following:

H -> H+ + e-

This positively charged hydrogen (H+ on the products side) is considered a Cation (cation's are positive as they have a T in them that looks like a +, anions don't have a T so they are what we call negatively charged anions).

Answer 2

Positive ions are formed when atoma lose valence electrons. Oppositely, negative ions are formed when atoms gain electrons. 2) Nitrogen will gain three electrons, sulfur will gain two, barium will lose two, and litium will lose one. Hope this helps!

Answer 3

An ION !!!

If it loses electron(s) to become M^(+) it is a CATION

If it gains electron(s)to become X^(-) it is an ANION/

Answer 4

When an atom loses or gains an electron or proton, it gains a charge. The charge can be either positive or negative.

Answer 5

They become ions; a negative ion (anion) after the gain of electrons or a positive ion (cation) after the loss of electrons.

Answer 6

An electric charge

Answer 7

More stable

And an ion

Answer 8

It becomes a charged ion.
