Bromine is a non‑metal in Group 17. At room temperature it is a liquid. Which statement explains this physical state?
- Bromine molecules have weak intermolecular forces that allow them to move but stay close together.
- Bromine atoms form a giant ionic lattice that partially melts at room temperature.
- Bromine has delocalised electrons that make it flow like a liquid metal.
- Bromine molecules have no forces between them, so they must be a liquid.
