(a)
Interpretation: The formula for the ions of
Concept Introduction: Ions are formed when electrons are lost or gained by an atom to attain noble gas configuration or to complete the octet. Here, metals lose electron/s to form positively charged ions or cations and non-metals gain electron/s to form negatively charged ions or anions. Ionic compounds are formed when these cations and anions are combined in fixed ratios. They are combined in such a way that the total charge of the ionic compound is zero.
(a)
Answer to Problem 44A
Explanation of Solution
The given ionic compound is KCl. Here, K is metal and Cl is non-metal. Potassium (K) belongs to group 1 thus; K has one valance electron, and it can lose one electron to form
The formula of ions of KCl is
