Bromine is a liquid at room temperature while chlorine is a gas. Both are Group 17 elements. Which statement explains this difference in state?
- Br₂ has stronger intermolecular forces than Cl₂ because its molecules are larger.
- Br₂ has stronger covalent bonds within its molecules than Cl₂.
- Br₂ has more electrons in its outer shell than Cl₂, so it must be a liquid.
- Br₂ has a giant lattice while Cl₂ has simple molecules.
