How does metallic character change as you move across a period in the periodic table?

Back

The metallic character of the elements decreases as you move from left to right across the periodic table.

Front

What happens to ionization energy as you move across a period from left to right?

Back

Ionization energy increases as you move from left to right across a period.

Front

Front

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

Back

Ionization energy generally decreases as you move down a group in the periodic table.

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius increases, ionization energy decreases.
