The atoms in metals experience metallic bonding.
Metallic bonding is the strong attraction between the oppositely charged metal cations and the free electrons.
The attraction must be broken to melt or to boil a metal. The attractions must be partially overcome to melt it and completely overcome to boil it.
These attractive forces are relatively strong, so metals have boiling and melting points which are higher than SATP.
This means that they are solids at SATP.
