Multiple Choice

The modern periodic table is arranged by increasing

• mass

• atomic number

• reactivity

• ionization energy

Find the Trend!

• As we add energy levels the atomic radius increases

• As we add protons to the nucleus the radius decreases

• The magnetic pull between protons and electrons is the key to this trend
