Back

Radon (Rn) has the largest atomic radius in Group 18.

Front

How does electronegativity change in Group 16 as you move down the group?

Back

Electronegativity decreases as you move down Group 16.

Front

What is ionization energy?

Back

The energy required to remove an electron from a gaseous atom.

Front

Front

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

Back

Atomic radius increases as you move down a group.

Front

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

Back

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

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius increases, ionization energy decreases.

Front

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

Back
