It is easy to understand how two electrons (one with spin up, one with spin down) can fill the 1s shell for a helium atom. How is it possible that eight more electrons can fit into the 2s2 p level to complete the 1s2s22p6 shell for a neon atom?
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.
