What neutral atom is isoelectronic with nitrogen?

Nitrogen (N) has 7 electrons in total. 2 in its first orbit and 5 in its second orbit (only has two orbits because it is in the second period of the Periodic Table). For a full, outer shell/orbit (8 electrons), it needs 3 more electrons.

5+3 = 8

Nitrogen has a charge of 3- which means it needs 3more electrons. If you add how many electrons it has gainedto the total number of electrons Nitrogen has (7) then you will find the element it is isoelectronic with.

7+3 = 10

Now find the element with 10 electrons (# of electrons = # of protons & # of protons = the atomic number of an element).

Neon (Ne) on the periodic table has an atomic number of 10 so therefore, Ne/Neon is the isoelectronic atom with Nitrogen.
