Mercury is the only metal that is liquid at 0ºC. This is due to its : — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Mercury is the only metal that is liquid at 0°C. This is because the effective nuclear charge is very high, as a result, mercury has high ionization energy and the bonds between mercury atoms are very weak. Therefore, though mercury is a metal but it is liquid at 0°C.
