Answer:
The total number of valence electrons in a n3- ion is 8 electrons.
Explanation:
Valence electrons are the electrons present in outermost shell of an atom.
They are responsible for chemical properties of the atom.
Nitrogen atomic number is 7.
Electronic configuration [He]2s2 2p3
There are 5 valence electrons. 2 electrons in s orbitals and 3 electrons in p orbital.
But 3- charge is present on Nitrogen .
Add 3 in valence electrons of nitrogen to get valence electrons of n3-.
5+3=8
8 electrons is the correct option.
