What is electronegativity?

Back

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

Front

What happens to electronegativity across a period in the periodic table?

Back

Electronegativity increases across a period from left to right.

Front

What happens to electronegativity down a group in the periodic table?

Back

Electronegativity decreases down a group.

Front

Define ionization energy.

Back

Ionization energy is the energy required to remove an electron from an atom.

Front

What is the trend of ionization energy across a period?

Back

Ionization energy increases across a period.

Front

What is the trend of ionization energy down a group?

Back

Ionization energy decreases down a group.

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the trend of atomic radius across a period?

Back

Atomic radius decreases across a period.

Front

What is the trend of atomic radius down a group?

Back

Atomic radius increases down a group.

Front

What is the relationship between atomic radius and electronegativity?

Back

As atomic radius increases, electronegativity generally decreases.
