What is the positive charge on the nucleus of an atom due to ?

The charge on a nucleus is

The positive charge of an atom is.

The magnitude of charge on the electron is 4.8 xx 10^(-10) e.s.u. What is the charge on the nucleus of a helium atom?

A nucleus of an atom is stable due to

According to Rutherford, the positively charged nucleus of the atom has a radius of about

Assertion: An atom of a magnetic material behaves as a dipole because of positive charge on the nucleus. Reason: Charge is responsible for dipole moment.

According to early model of an atom,the atom is considered it to have a positively charged point nucleus of charge Ze surrounded by a uniform density of negative charge up to a radius R . The atom as a whole is neutral. The electric field at a distance r from the nucleus is (r lt R)
