What type of bonding would you expect between the following pairs of elements?
(i) Calcium and Oxygen
(ii) Carbon and Chlorine
(iii) Hydrogen and Chlorine.
(i) Ionic bonding exists between calcium and oxygen as calcium loses 2 electrons and oxygen gains it, to fulfill their octet.
(ii) Covalent bonding exists between carbon and chlorine as they share electrons to fulfill their octet.
(iii) Covalent bonding exists between hydrogen and chlorine as they share electrons to fulfill their octet.
