Review for Ionization and Electronegativity

Front

What is ionization energy?

Back

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

Front

How does ionization energy change across a period in the periodic table?

Back

Ionization energy generally increases across a period from left to right due to increasing nuclear charge.

Front

How does ionization energy change down a group in the periodic table?

Back

Ionization energy decreases down a group due to increased distance between the nucleus and the outermost electrons, as well as increased electron shielding.

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 the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

What is the trend of electronegativity across a period?

Back

Electronegativity increases across a period from left to right.

Front

What is the trend of electronegativity down a group?

Back

Electronegativity decreases down a group.

Front

Which group of elements has the highest ionization energy?

Back

Noble gases have the highest ionization energy.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, elements with high ionization energy also have high electronegativity.

Front

What is the significance of ionization energy in chemical reactions?

Back

Ionization energy is significant because it influences how easily an atom can lose electrons and form positive ions.
