X+ne−→Xn−

The metals of group IA form +1 ions because the highest oxidation number is always equal to the group number of that element. Thus, the charge on group IA elements is +1. Similarly, group IIA elements form +2 ions by losing two electrons and have an oxidation number of +2. The non-metal gains these electrons to form anions with −1 and −2 charge.

The stoichometric coefficents are multiplied with the compounds or species in the chemical equation to have equal number of atoms on both side of the equation. The equation is known as a balanced chemical equation if there are equal number of atoms of each element in both the product and reactant side.

For the naming of an ionic compound, the cation is always named first followed by the anion and the anion ends with the “-ide”.

(a)

Interpretation Introduction

Interpretation: To write the balanced chemical equation for the formation of NaBr.

Concept Introduction: Main group elements are categorised as s-block and p-block elements. The s-block elements includes metals belonging to group 1 and group 2 and elements from group 13 to 18 are referred to as p-block elements. The reaction of themetals of main group elements with the non metals forms ionic compounds.

Ionic compounds are formed by the loss of electrons from the metal which are gained by the non metals. The metal gets positively charge and the non metal attains a negative charge thus forming cations and anions respectively. They do so to attain a noble gas configuration or to attain stability.
