Electron shells, orbitals, and sub-orbitals.
The second shell of an atom has two sub-shells: the 2s and 2p sub-shells. The 2s sub-shell can hold a maximum of 2 electrons, while the 2p sub-shell can hold a maximum of 6 electrons, allowing the second shell to accommodate a total of 8 electrons.
Negatively charged sub-atomic particle: electron. Positively charged sub-atomic particle: proton. Neutrally charged sub-atomic particle: neutron.
A sulfur atom has 3 electron shells.
A sodium atom has 3 energy shells.
Electrons are found in shells around the central part of an atom. These shells represent different energy levels in which electrons can be located. The arrangement and movement of electrons in these shells determine the chemical properties of the atom.
A bismuth atom has 6 electron shells.
The electron can either be by itself outside of an atom, or can be in an atom in a series of energy 'shells' outside of the nucleus.
Argon (Ar): 18 electrons confugered in three shells (no. 1, 2, 3): (2, 8, 8) and with sub-shells (s and p): (1s2, 2s2 2p6, 3s2 3p6)
Four sub-shells: s, p, d, f . Only artificially / theoretically in quantum mechanics there is a 5th sub shell 'g' and maybe 'h' is the 6th
