Detailed explanation-1: -The correct answer is Mercury. Mercury metal remains liquid at ambient normal temperature.
Detailed explanation-2: -Key Takeaways: Liquid Elements They are mercury (a metal) and bromine (a halogen). Four other elements are liquids slightly warmer than room temperature. They are francium, cesium, gallium, and rubidium (all metals).
Detailed explanation-3: -It stabilizes the 6s orbital. Therefore it is difficult to remove the outer electrons unlike in other metals. Hence mercury cannot easily form bonds with other elements. This is the reason why mercury exists in a liquid state.
Detailed explanation-4: -The only liquid elements at standard temperature and pressure are Bromine (Br) and Mercury (Hg). Although, elements Caesium (Cs), Rubidium(Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.
