... A period is likened to an energy level when completing energy level diagrams. Moving left to right, the attraction between the valence electrons and the nucleus increases, this causes the atomic radius to decrease, and electronegativity and ionization energy to increase. ...

... Orbitals in the same shell (3s vs. 3p) are not degenerate anymore. The higher the nuclear charge (the larger the number of protons Z), the more the electrons are attracted towards it. Thus any given orbital shrinks with growing Z and the corresponding energy becomes more negative. The orbitals can ...
