The Periodic Table
... Reason: Same principal quantum number going across the period. More protons are added going across the period. The protons have a stronger pull on the electrons. The strong attractive forces between the protons and the outermost (valence) electrons shrinks the orbitals and makes the atoms smaller. E ...
