Periodic Trends Practice

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has a higher electronegativity: Iodine or Cadmium?

Back

Iodine has a higher electronegativity than Cadmium.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

Arrange the following elements in order of increasing ionization energy: Lithium, Carbon, Neon.

Back

Lithium, Carbon, Neon.

Front

Which element has greater ionization energy: Lead or Silicon?

Back

Silicon has greater ionization energy than Lead.

Front

What trend is observed in ionization energy as you move across a period in the periodic table?

Back

Ionization energy generally increases as you move from left to right across a period.

Front

What trend is observed in ionization energy as you move down a group in the periodic table?

Back

Ionization energy generally decreases as you move down a group.

Front

What happens to the atomic radius as you move across a period?

Back

The atomic radius decreases as you move from left to right across a period.

Front

What happens to the atomic radius as you move down a group?

Back

The atomic radius increases as you move down a group.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.
