What is electronegativity?

Back

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

How does electronegativity change across a period in the periodic table?

Back

Electronegativity generally increases from left to right across a period.

Front

How does electronegativity change down a group in the periodic table?

Back

Electronegativity generally decreases as you move down a group.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from a neutral atom in the gaseous phase.

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

Back

Ionization energy generally decreases as you move down a group.

Front

What is the relationship between electronegativity and bond strength?

Back

A bond between atoms with a larger difference in electronegativity is generally stronger.

Front

What is the trend of atomic radius across a period?

Back

Atomic radius generally decreases from left to right across a period.

Front

What is the trend of atomic radius down a group?

Back

Atomic radius generally increases as you move down a group.

Front

What is the significance of a high first ionization energy?

Back

A high first ionization energy indicates that an atom holds its electrons tightly and is less likely to lose them.
