(a) the bond which will form between calcium and chlorine will be an ionic or electrovalent bond.
(b) The calcium being a metal, has a tendency to lose electrons, and will lose its two outer valence electrons to form its octet and Ca2+ ion. The chlorine atom has a tendency to gain an electron as it is a non-metal. 1 Chlorine atom can gain only 1 electron to complete its octet. So, 2 Cholrine atoms gain the 2 electrons from calcium and form 2[Cl-] ions. Now, the electrostatic force of attraction begins to act between the oppositely charged particles and they form a electrostatic bond. The compound formed is CaCl2
(c) chemical formula for the compound= CaCl2.
Your one thumbs up will help me lot. Thanks!
