Q. Ramu has an element $X$ with an Atomic Number of 13, while Somu has an element $Y$ with an Atomic Number of 16. If Ramu and Somu mix those elements and heat it, a new compound of $Z$ is formed.
Keeping this mind and answer the following question.
i) Write the electronic configuration of $X$.
ii) Write the electronic configuration of $Y$.
iii) Which one is a metal and which is a non-metal?
iv) What is the valency of $X$?
v) What is the valency of $Y$?
vi) Write the formula of $Z$.
