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

Which atom has the largest atomic radius?

Back

Francium has the largest atomic radius among the given options.

Front

Which periodic group has the smallest atomic radius?

Back

Noble Gases have the smallest atomic radius.

Front

In which group do alkali metals belong?

Back

Alkali metals belong to Group 1 of the periodic table.

Front

Which atom would you expect to have the largest atomic radius: Li, K, Ca, or Br?

Back

Potassium (K) would have the largest atomic radius.

Front

What happens to atomic size as you move across a period in the periodic table?

Back

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

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 and pulls electrons closer to the nucleus.

Front

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

Back

Atomic radius increases as you move down a group.

Front

Why does atomic radius increase down a group?

Back

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

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius increases, ionization energy decreases.
