(a)[1]
State phosphorus's electronic configuration.
(b)[1]
Explain why the boiling point of bismuth is easier to predict than its melting point.
(c)[1]
Use the table data to explain why antimony is a liquid at $1000\,^{\circ}\text{C}$.
(d(i))[1]
Draw a dot-and-cross diagram to represent the bonding in $\text{N}_2$. Include only the outer-shell electrons.
(d(ii))[1]
Explain, in terms of structure and bonding, why nitrogen's melting point is low.
(e)[2]
Predict any two physical properties of bismuth.
(f)[3]
Calculate the volume, in dm$^3$, occupied by 19.2 g of nitrogen at room temperature and pressure. Give your answer to two significant figures.
