Solution

## The electrons present in the outermost orbit or valence shell are called valence electrons.Atomic number of nitrogen ($\mathrm{N}$) = $7$Therefore, distribution of electrons = $2,5\mathrm{or}$ $\mathrm{K}\mathrm{L}\phantom{\rule{0ex}{0ex}}25$Hence $\mathbit{5}\mathbit{}$valence electrons are present in nitrogen having atomic number 7.
