Question

Mercury is liquid at room temperature. This is due to * 1 point high viscosity of mercury large surface tension of mercury weak metallic bonding & van der waals forces strong metallic bonding & van der waals forces

Answer 1

Answer:

"The high surface tension of mercury is due to intermetallic bonding. This bonding creates a strong "desire" for Hg atoms to interact with each other, versus their surroundings. In contrast, the surface tension of water is due to hydrogen bonding, a much weaker force that is easier to overcome." I found this answer on quora and it seems good because Hg atoms share an intermetallic bond which is much stronger that the hydrogen bonds between water molecules."
