Atomic Radius

Front

What is atomic radius?

Back

The distance from the nucleus to the outer boundary of an atom.

Front

Which element has the largest atomic radius: copper, zinc, silver, or cadmium?

Back

Silver.

Front

As you move across the periodic table, what happens to atomic size?

Back

Atoms tend to get smaller because they have more protons.

Front

What causes atoms to get larger as you move down the periodic table?

Back

Atoms have more energy levels.

Front

How does the number of protons affect atomic radius?

Back

The more protons there are, the stronger the pull on the electrons, leading to a smaller atomic radius.

Front

What is the trend in atomic radius as you move from left to right across a period?

Back

Atomic radius decreases.

Front

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

Back

Atomic radius increases.

Front

Why do larger atoms have more energy levels?

Back

Because they have more electrons, which occupy higher energy levels.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.

Front

Define effective nuclear charge.

Back

The net positive charge experienced by an electron in a multi-electron atom.
