electron cloud
300
A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge

Isotope
400
Any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table.

400
The modern model of the atom shows that electrons are
found in regions called orbitals.
500
The region of negative charge surrounding an atomic nucleus that is associated with an atomic orbital.
Electron Cloud
500

Metals
500
The reactivity of the atom is determined by the atom's number of
valence electrons.
