Ion

an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.

Common ION

Electron is negatively chargedProton is positively charged

Do you know ?

During chemical reactions,some atoms lose or gain electrons

Losing electrons

atom become POSITIVE ION

eg

Na

loses one electron

Na

+

(sodium atom)

Gaining electrons

ion with more electrons than protons, giving it a net negative charge

atom become NEGETIVE ION

eg

Cl

Cl

-

gains one electron

(sodium ion)

(chlorine ion)

(chlorine atom)

ion with less electrons than protons, giving it a net positive charge

Opposite charge attract.The compounds form by attraction of positive and negetive ions are called ionic compounds

monotomic Ion

an ion consisting of a single atom

polyatomic Ion

an ion consisting of two or more atoms
