Ionization Energy

Front

What is ionization energy?

Back

Energy required to remove an electron from an atom.

Front

Which element has the highest ionization energy: Li, K, Fr, or Na?

Back

Lithium (Li) has the highest ionization energy.

Front

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

Back

Ionization energy generally increases across a period.

Front

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

Back

Ionization energy generally decreases down a group.

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 significance of a large jump between IE1 and IE2?

Back

A large jump indicates that an electron is being removed from a much more stable electron configuration.

Front

Which has a higher second ionization energy: Na or Mg?

Back

Sodium (Na) has a higher second ionization energy than Magnesium (Mg).

Front

What is the relationship between electron affinity and ionization energy?

Back

Both are measures of how an atom interacts with electrons; higher ionization energy often correlates with higher electron affinity.

Front

Define the term 'electron configuration'.

Back

The distribution of electrons in an atom's orbitals.

Front

What is the electron configuration of Sodium (Na)?

Back

1s² 2s² 2p⁶ 3s¹.
