Variable melting points
why metallic solids are soft to hard
metallic bonds
Respectively are Calcium cabonate, Tungsten and Diamond (most probably)
There are four types of crystalline solids. The four types of crystalline solids includes the ionic solid, molecular solids, atomic solids and the metallic solids.

why metallic solids are soft to hard
Metallic solids are composed of individual atoms.
metallic bonds
Brittleness. Reason: Non-metallic solids are usually brittle.
Metallic
The solid carbon compounds are mostly molecular solids.
no
They tend to be, yes
Respectively are Calcium cabonate, Tungsten and Diamond (most probably)

All Metals except Hg (Mercury) are solids at room temperature.
It can be categorised into -Ionic -Covalent molecular -Metallic -Covalent network
