The nitrogen atom has \( 7\) protons and \(7\) electrons, the nitride ion \(({N^{3 - }})\) will have
1 \(7 \) protons and \(10 \) electrons
2 \(4\) protons and \(7\) electrons
3 \(4 \) protons and \(10 \) electrons
4 \(10\) protons and \(7\) electrons
Explanation:
(a) No. of \(P = Z = 7;\) No. of electrons in \({N^{3 - }} = 7 + 3 = 10.\)

Rutherford's experiment on scattering of particles showed for the first time that the atom has
1 Electrons
2 Protons
3 Nucleus
4 Neutrons
Explanation:
Rutherford's experiment on scattering of \(\alpha\)-particles showed for the first time that the atom has nucleus. He observed that the positively charged \(\alpha\)-particles were repelled and deflected by the positive charges in the atom. Rutherford's named this positively charged portion of atom as nucleus.
