Question

The number of electrons shared by each N atom in N2 is ?​

Answer 1

nitrogen has 5 valence electrons (it needs a further 3). Two nitrogen atoms can share 3 electrons each to make a N2 molecule joined by a 'triple covalent bond'.

Answer 2

$one \: nitrogen \: electron = 3 \times 6.022 \times {10}^{23} \times 1.6 \times {10}^{ - 24} \\ = 4 \times {10}^{ - 2} = 4 cent \\ two \: nitrogen \: electron = 2 \times 4centi = 8centi \: ans.$
