+2 or -2? Either way, nothing special happens.
This atom gain two electrons and become an anion.
This atom become a positive ion (cation).
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
Helium is a neutral atom that has several isotopes and can become an ion.
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
it becomes an ion
the radius increases when atom is converted to negatively charged anion.
well The electrons on that shell have nowhere to go so they jump off and become ionised
An atom looses or gains electron to become ion. Ions are +ve and -ve atoms.
IONS OS ION ^^A charged atom is called an ion
It will become a soft ion.
A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen atom.
