The luster of a metal is due to
presence of free electrons
high polishing on the surface
high density
chemical inertness

Nitrogen is chemically inert due to

Statement- 1 : High thermal conductivity of metals is due to presence of free electrons. Statement- 2 : Electrons at same temperature have very high average velocity than atoms.

Boiling point of water is high due to presence of

We know that copper is a conductor of electricity due to presence of free electrons in it. Assume that on an average each copper atom provides one free electron. Find the number of free electrons per unit valume of copper. The density of copper is approximately 9,000 kg / m^3 and its atomic mass is 63.5 u.

Due to the presence of an unpaired electron, free radicals are:

Due to the presence of an unpaired electron free radicals are
