Rutherford's model of atoms represented the solar system. Where the positive charge is at the centre like the sun and electrons revolve around it like a planet. Therefore, his model is known as planetary model.
The answer is B Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell. Another example of a nonpolar covalent bond is found in the methane (CH4) molecule.
