Front

What is the trend of atomic radius as you move down a group in the periodic table?

Back

Atomic radius generally increases as you move down a group.

Front

What is the trend of atomic radius as you move from right to left across a period?

Back

Atomic radius generally increases as you move from right to left across a period.

Front

What is electronegativity?

Back

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

Front

What is the general trend of electronegativity in the periodic table?

Back

Electronegativity generally increases from left to right across a period and decreases down a group.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases.
