Question

Which of the following metal exists in the liquid state?

Options

• Na

• Ag

• Cr

• Hg

Answer 1

Hg

Explanation:

Hg (Mercury) is the only common metal on the periodic table that exists as a liquid at room temperature. It has an extremely low melting point (−38.83°C) due to its unique electronic structure, which prevents its atoms from bonding tightly. In contrast, sodium (Na), silver (Ag), and chromium (Cr) maintain strong metallic bonds and exist as solid metals under normal conditions.
