An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
Cations.
This atom gain two electrons and become an anion.
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
it becomes happy!
the atom becomes negatively charged
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
When an atom loses an electron, it becomes a cation and has a positive charge.
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
It becomes a negatively charged ion.
The atom absorbs energy, and one or more electrons move to a higher electron shell
It becomes a negatively charged ion with a charge of 1-.
It becomes C+4 ion.
