2 core electrons and 8 valence electrons are there in N3- ion.
a core electron, is an electron that isn't a valance electron. That means any electron that is not on the outer shell of an atom
N3- , O2- , F- , Na+ , Mg2+ , Al3+ all have the same electron configuration as Neon.
Nitrogen is the element located in group 15, period 2. Thus, its electron configuration is 1s2 2s2 2p3. That means that 2 is its valence shell and 1 is its core shell. Therefore, nitrogen has 2 core electrons and 5 valence electrons.
The chemical formula for a nitride ion is N-3.
Ne (neon) completes n3.
Neon

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
a core electron, is an electron that isn't a valance electron. That means any electron that is not on the outer shell of an atom
The electron is an elementary particle. This means that it cannot be broken down further. Therefore, an electron does not have a "core".
N3- , O2- , F- , Na+ , Mg2+ , Al3+ all have the same electron configuration as Neon.
Nitrogen is the element located in group 15, period 2. Thus, its electron configuration is 1s2 2s2 2p3. That means that 2 is its valence shell and 1 is its core shell. Therefore, nitrogen has 2 core electrons and 5 valence electrons.

You think probable to electron configuration.
The chemical formula for a nitride ion is N-3.
H- has the noble gas config. of He(helium). N3- has a electronic configuration of Ne(neon). Ni2+ doesn't have the stable config. of any noble gas.It's config. is [Ar]4s23d10.
Helium(He)
