Turning Point
Generally, how do atomic masses vary
throughout the periodic table of the elements?
1. They increase from right to left and top to
bottom.
2. They increase from left to right and bottom
to top.
3. They increase from left to right and top to
bottom.
4. They increase from right left and bottom to
top.
Which of the following ordered pairs of
elements shows an increase in atomic number
but a decrease in average atomic mass?

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

increases.
• B increases and the electronegativity
decreases.
• C decreases and the electronegativity
increases.
• D decreases and the electronegativity
decreases.
