Ionization Energy Trends

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom or ion.

Front

Back

Calcium, Iron, Copper.

Front

What happens to ionization energy as you move across a period in the periodic table?

Back

Ionization energy increases.

Front

What happens to ionization energy as you go down a group in the periodic table?

Back

Ionization energy decreases.

Front

Why does ionization energy decrease as you go down a group?

Back

Outer electrons are further away from the nucleus, feel less pull from the nucleus, and are easier to remove.

Front

What is the trend of ionization energy in relation to atomic size?

Back

As atomic size increases, ionization energy decreases.

Front

What is the relationship between ionization energy and electronegativity?

Back

Elements with high ionization energy typically have high electronegativity.

Front

How does the ionization energy of noble gases compare to other elements?

Back

Noble gases have the highest ionization energies due to their stable electron configurations.
