<u>Answer:</u>

Ion is a charged particle.

A neutral atom contains equal number of positive protons and negative electrons

When an electron is lost or gained the atom becomes a charged particle which is called as an ION.

For example

Na is an atom which contains 11 electrons and 11 protons (= to atomic number)

When Na loses an electron it will have 11 positive proton and 10 negative electron and Thus, Na will become $Na^+$ , a charge particle which we call it as sodium ion.

Cl is an atom which contains 17 electrons and 17 protons (= to atomic number)

When Cl loses an electron it will have 17 positive proton and 18 negative electron and Thus, Cl will become $Cl^-$ , a charge particle which we call it as chloride ion.

When an ion is positively charged it is called as a cation

When an ion is negatively charged it is called as an anion.

Beryllium forms $Be^{+2}$ cation.we see this in Beryllium chloride $BeCl_2$ .

If $BeCl_2$ is present in water it forms Beryllium ions which is in Hydrated form that is $H_2 O$ molecules are present in its ion $[Be(H_2 O)_4 ]^{+2}$ .
