Atomic Radius Trend

Front

What happens to atomic radius as you move across the periodic table?

Back

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

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

Why do atoms get smaller as you move across a period?

Back

Atoms get smaller because they have more protons, which increases the positive charge in the nucleus, pulling electrons closer.

Front

Which element has the largest atomic radius in Group 18?

Back

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

Front

True or False: Metals are good conductors of heat and electricity.

Back

True.

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

How does the number of electron shells affect atomic radius?

Back

More electron shells result in a larger atomic radius.

Front

What is the effect of increased nuclear charge on atomic radius?

Back

Increased nuclear charge pulls electrons closer to the nucleus, resulting in a smaller atomic radius.

Front

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

Back

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

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius decreases, ionization energy generally increases.
