Atomic Radius

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 trend in atomic radius is observed across a period in the periodic table?

Back

Atomic radius decreases across a period.

Front

What trend in atomic radius is observed down a group in the periodic table?

Back

Atomic radius increases down a group.

Front

Which atom has the largest atomic radius?

Back

Francium.

Front

Why do atoms get larger as you move down the periodic table?

Back

Atoms have more energy levels as you move down the periodic table.

Front

What is the relationship between atomic radius and metallic character?

Back

As atomic radius increases, metallic character generally increases.

Front

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

Back

Nonmetals generally have a smaller atomic radius than metals in the same period.

Front

What effect does increasing nuclear charge have on atomic radius?

Back

Increasing nuclear charge tends to decrease atomic radius due to greater attraction between the nucleus and electrons.

Front

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

Back

Atomic radius decreases from left to right across a period and increases from top to bottom in a group.
