Vedclass · Answer

(C) Given that $Z$ is an alkali metal with atomic number $a+2$. Alkali metals belong to Group $1$ of the periodic table. If $Z$ is an alkali metal,then $Y$ (atomic number $a+1$) is a noble gas (Group $18$) and $X$ (atomic number $a$) is a halogen (Group $17$). $X$ is a non-metal (halogen) and $Z$ is a metal (alkali metal). The bond formed between a metal and a non-metal is typically ionic in nature. Therefore,the compound formed by $X$ and $Z$ is ionic.

The atomic numbers of the elements $X, Y, Z$ are $a, a+1, a+2$ respectively. $Z$ is an alkali metal. The nature of bonding in the compound formed by $X$ and $Z$ is
