Document Summary

Elements have similar chemical properties when they are closest together on the periodic table, same. Screening of the nuclear charge by core electrons in atoms is more efficient than that by valence electrons. The force increases as the nuclear charge increases and decreases as the electron moves farther from the nucleus. The effective nuclear charge acting on an electron in an atom is smaller than the actual nuclear charge because the effective nuclear charge includes the effect of the other electrons in the atom. Increasing atomic radius goes from top to bottom; right to left. First ionization increases from bottom to top; left to right (smaller atoms have higher ionization energies). Right to left; top to bottom increasing metallic character across the periodic table (same as atomic radius) Transition metals within a period differ mainly in the number of d electrons.
