Back

Electronegativity increases.

Front

What happens to electronegativity as you move from top to bottom within a group?

Back

Electronegativity decreases.

Front

True or False: The atomic radius increases as you move left on the periodic table.

Back

True.

Front

Why do atoms tend to get smaller as you move across the periodic table?

Back

Because the atoms have more protons.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

Define electronegativity.

Back

Electronegativity is a measure of the ability of an atom to attract electrons.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases.
