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 energy947 kJ mol⁻¹
Covalent radius119 pm
Electronegativity2.18 Pauling
Arsenic sublimes at 887 K at 1 atm; it melts at 1090 K only under about 3.6 MPa, which is why the melting point exceeds the boiling point here.
Description of this simulation
Arsenic is neutral here: 33 protons are balanced by 33 electrons across shells 2, 8, 18, 5.

What this model shows — and what it simplifies
Educational ModelThe nuclear charge stays fixed at 33 protons, which is what defines Arsenic.
Where do we see this in real life?
The electron count and measured properties of Arsenic help determine how it bonds, reacts and is identified in chemical materials.
