Atomic Radius Trend

Front

What is atomic radius?

Back

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

Front

How does atomic radius change across a period in the periodic table?

Back

Atomic radius decreases as you move from left to right across a period due to increasing nuclear charge.

Front

How does atomic radius change down a group in the periodic table?

Back

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

Front

What is the trend of atomic radius in relation to electronegativity?

Back

Generally, as atomic radius increases, electronegativity decreases because the distance between the nucleus and the bonding electrons increases.

Front

Which element has a larger atomic radius: Sodium or Chlorine?

Back

Sodium has a larger atomic radius than Chlorine.

Front

What is the reason for the increase in atomic radius down a group?

Back

The increase in atomic radius down a group is due to the addition of electron shells, which outweighs the effect of increased nuclear charge.

Front

What is the relationship between atomic radius and metallic character?

Back

As atomic radius increases, metallic character increases because larger atoms tend to lose electrons more easily.

Front

Which has a larger atomic radius: Strontium or Magnesium?

Back

Strontium has a larger atomic radius than Magnesium.

Front

What happens to atomic radius when moving from a metal to a non-metal?

Back

Atomic radius generally decreases when moving from metals to non-metals across a period.

Front

What is the effect of increased protons on atomic radius?

Back

Increased protons in the nucleus pull the electron cloud closer, resulting in a smaller atomic radius.
