(a) The nitrogen atom has one electron in each of the 2px,2py and 2pz orbitals. By using the form of the angularwave functions, show that the total electron density,c2(2px) +c2(2py) +c2(2pz), is spherically symmetric(that is, it is independent of the angles u and f). Theneon atom, which has two electrons in each 2porbital, is also spherically symmetric.(b) The same result as in part (a) applies to d orbitals,thus a filled or half-filled subshell of d orbitals isspherically symmetric. Identify the spherically symmetric atoms or ions among the following: F=, Na, Si,S2-, Ar+, Ni, Cu, Mo, Rh, Sb, W, Au.

Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
Question
- (a) The nitrogen atom has one electron in each of the 2px,
2py and 2pz orbitals. By using the form of the angular
wave functions, show that the total electron density,
c2(2px) +c2(2py) +c2(2pz), is spherically symmetric
(that is, it is independent of the angles u and f). The
neon atom, which has two electrons in each 2p
orbital, is also spherically symmetric.
(b) The same result as in part (a) applies to d orbitals,
thus a filled or half-filled subshell of d orbitals is
spherically symmetric. Identify the spherically symmetric atoms or ions among the following: F=, Na, Si,
S2-, Ar+, Ni, Cu, Mo, Rh, Sb, W, Au.
