Two samples, P and Q, contain only carbon atoms. Information from models of their bonding is shown in the table.

Sample	Arrangement of carbon atoms	Bonding evidence
P	A flat layer one carbon atom thick	Each carbon atom has covalent bonds to three neighbouring atoms. Starting from any atom, a path of covalent bonds can reach every other atom in the sample.
Q	Many hollow cages arranged next to one another	A path of covalent bonds remains within one cage and cannot reach an atom in a neighbouring cage.

Explain which sample has a giant covalent structure and which sample consists of separate molecules.

Predict whether sample P conducts electricity. Explain your answer.
