Atomic Radius

Front

What is the definition of atomic radius?

Back

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

Front

Which element has the largest atomic radius in the periodic table?

Back

Francium (Fr) has the largest atomic radius in the periodic table.

Front

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

Back

Atomic radius increases as you move down a group due to the addition of energy levels.

Front

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

Back

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

Front

Which group of elements typically has the smallest atomic radius?

Back

Noble gases (Group 18) typically have the smallest atomic radius.

Front

What is the relationship between atomic radius and metallic character?

Back

As atomic radius increases, metallic character generally increases.

Front

Which element has a larger atomic radius: Strontium (Sr) or Zinc (Zn)?

Back

Strontium (Sr) has a larger atomic radius than Zinc (Zn).

Front

What causes the increase in atomic radius down a group?

Back

The increase in atomic radius down a group is caused by the addition of electron shells.

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

How does the atomic radius of nonmetals compare to that of metals?

Back

Nonmetals generally have smaller atomic radii compared to metals.
