Question

Aluminium atom has 13 protons and 14 neutrons. Chlorine atom has 17 protons and 18 neutrons.
When aluminium reacts with chlorine, aluminium atom donates three electrons (one electron to
each of the chlorine atoms) and chlorine atom gains one electron (three chlorine atoms each
gaining one electron). Aluminium becomes positively charged aluminium ion and chlorine
becomes negatively charged chloride ion. Thus, Aluminium chloride molecule is formed (AICI3).
- The chemical bond formed by transfer of electron/s is called ionic bond or electrovalent bond and
compounds formed are called ionic compounds or electrovalent compounds. Generally, the bond
formed between metals and non-metals is ionic bond.
