You can never say that any substance is a liquid, a solid, or a gas. Every substance you name can be all of those, depending on the TEMPERATURE.
At standard pressure . . .
-- Iodine is solid below 113.7°C, and gas above 184°C .
-- Bromine is solid below -7.2°C, and gas above 58.8°C .
-- "Room temperature" is considered to be the range from 20°C to 23.5°C.
-- Iodine is solid in that range.
-- Bromine one of only two elements that are known to be liquids AT ROOM TEMPERATURE. The other one is mercury ... a metal.
Iodine is a solid at room temperature, melting at 113.7 °C, while bromine is a liquid at room temperature due to its weaker intermolecular forces. The diatomic structure of both elements contributes to their differing states, with bromine's structure allowing it to remain liquid. Therefore, bromine is the only non-metal that is typically classified as a liquid under normal conditions.
