I.
An atomic orbital is a mathematical function that describes the wave-like
stationary motion for an electron in an atom. The orbital names (s, p, d, f, g,
h,...) are derived from the characteristics of their spectroscopic lines: sharp,
principal, diffuse and fundamental, the rest being named in alphabetical order.
Due to the quantization of the isotropic space in atoms, the s, p, d, f
correspond to azimuthal angular momentum quantum number
l
=0,1,2,3
respectively, each with a corresponding degeneracy of 2
l
+1 without counting
spin, and 2x(2l+1) counting spin.
II.
The eight columns of the periodic table are a result of the quantization of the
isotropic space in atoms: two s orbitals and six p orbitals. The chemical
properties of the atoms with the same number of electrons in these eight
orbitals are quite similar, therefore giving this most prominent feature of the
periodic table.
III.
Alkali metals refer to elements in the first column of periodic table with
hydrogen excluded.
