(a)
Interpretation: The complete balanced equation should be written for the given reaction.
Concept introduction: Main group elements are categorized as s-block and p-block elements. The s-block elements include metals belonging to group
Ionic compounds are formed by the loss of electrons from the metal which is gained by the nonmetals. 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.
Here, by losing electrons metal M achieve the noble gas configuration. These electrons are gained by the non-metals X as shown below.
The metals of group
The compounds of non-metals with oxides and hydrides are covalent compounds. This is because non-metals are less electropositive and the difference in electronegativity between two elements is less than
