Metallic
Amorphous solids are formed by the rapid cooling of a liquid. Then, when cooled the particles have no regular pattern like crystaline solids do.
It can be categorised into -Ionic -Covalent molecular -Metallic -Covalent network
Gaseous mixtures, metallic alloys,metallic agglomerations are some examples.
Metallic Bond .
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
Variable melting points
With some oxides metallic hydroxides are formed.
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.
