The ionization energy of an element indicates
the energy it takes to remove an electron
from the outermost energy level. As you move down
a group in the periodic table, the ionization energy
1. decreases because the electron

away from the nucleus.
• increases because the number of protons
increases.
• decreases because the number of neutrons
increases.
• increases because the size of the atom
increases.

The electronegativity of an element indicates
the relative ability of its atoms to attract electrons in a
chemical bond. As you move across a period(to the
right) in the periodic table, the atomic number
• A increases and the electronegativity
