Periodic Trends

Front

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

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

What is the trend in ionization energy as you move across a period from left to right?

Back

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

Front

What is the trend in metallic character as you move down a group?

Back

Metallic character increases as you move down a group.

Front

What is the trend in ionization energy as you move down a group?

Back
