why metallic solids are soft to hard
metallic bonds
Variable melting points
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.
Ions
Metallic solids are composed of individual atoms.
Lithium is soft, metallic, and shiny.
metallic bonds
The property of a solid molecular compound is soft. These are soft because solids are non-conductors of electricity in form.
Brittleness. Reason: Non-metallic solids are usually brittle.
Metallic
Rocks can be qualified for a solid. So can ice. Objects that are hard can usually be a solid.
The solid carbon compounds are mostly molecular solids.
no
Vanadium is a soft silvery white toxic metallic element used in steel alloys. Cobalt is a hard ferromagnetic silver-white bivalent or trivalent metallic element. Strontium is a soft silver-white or yellowish metallic element of the alkali metal group.
They tend to be, yes
