Question

atom is the dash charge in the nucleus of an atom is equivalent to dash number of an atom

Answer 1

An atom is one of the basic units of matter. Everything around us is made up of atoms. An atom is a million times smaller than the thickest human hair. The diameter of an atom ranges from about 0.1 to 0.5 nanometers (1 × 10−10 m to 5 × 10−10 m).

All the atoms of an element are not alike, however. For example, a second kind of hydrogen exits which is present in every sample of the gas no matter where it is obtained. It weighs twice as much as the more common hydrogen and is called deuterium or heavy hydrogen. The diameter of an atom for this type of hydrogen differs from the more common type.
