Atomic Radius Trend

Front

What is the atomic radius?

Back

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

Front

Which periodic group has the smallest atomic radius?

Back

Noble Gases.

Front

What happens to atomic radius as you move from left to right across a period?

Back

The atomic radius generally decreases.

Front

What happens to atomic radius as you move down a group in the periodic table?

Back

The atomic radius generally increases due to the addition of energy levels.

Front

Why do metals have larger atomic radii compared to nonmetals?

Back

Metals have fewer valence electrons and a weaker attraction to the nucleus, resulting in a larger radius.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius decreases across a period and increases down a group.

Front

What is the reason for the decrease in atomic radius across a period?

Back

Increased nuclear charge pulls electrons closer to the nucleus.

Front

Which element has a larger atomic radius: Strontium or Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius decreases, ionization energy increases.

Front

What is the effect of additional energy levels on atomic radius?

Back

Additional energy levels increase the distance between the nucleus and the outermost electrons, resulting in a larger atomic radius.
