Explanation mode
Core label represents the fixed nuclear charge; individual neutrons are not inferred from standard atomic weight.
Reviewed atomic properties
Unavailable measurements remain explicitly unavailable.
First ionization energy1402.3 kJ mol⁻¹
Covalent radius71 pm
Electronegativity3.04 Pauling
The nitrogen anion is unbound, so nitrogen has no positive electron affinity — a direct consequence of its half-filled 2p subshell.
Description of this simulation
Nitrogen is neutral here: 7 protons are balanced by 7 electrons across shells 2, 5.

What this model shows — and what it simplifies
Educational ModelThe nuclear charge stays fixed at 7 protons, which is what defines Nitrogen.
Where do we see this in real life?
The electron count and measured properties of Nitrogen help determine how it bonds, reacts and is identified in chemical materials.
