2. It is not possible to see an atom with the naked eye because of its extremely small size (atomic radius is of the order of 10-10 m).

Answer 2

Answer:

1. Atomic mass refers to the mass of an atom. It depicts how many times an atom of an element is heavier than one-twelth (1/12th) the mass of one atom of carbon-12 of mass of one carbon atom. ... It is measured in unit called amu (atomic mass unit).
