Introduction to Periodic Table Trends

Front

Atomic radius

Back

The size of the atom

Front

What happens to the atomic radius as you go from top to bottom within a group in the periodic table?

Back

It increases

Front

As you move down the periodic table, why do atoms get bigger?

Back

The atoms have more energy levels.

Front

What happens to the atomic radius as you go from left to right within a period in the periodic table?

Back

It decreases

Front

Why does atomic radius decrease from left to right across a period?

Back

Increasing effective nuclear charge (from increasing protons in the nucleus)

Front

Which atom has the largest atomic radius? Options: potassium, rubidium, francium, cesium

Back

francium

Front

Ionization energy

Back

The amount of energy needed to remove an electron from an atom

Front

How does ionization energy change from left to right within a period in the periodic table?

Back

It increases

Front

How does ionization energy change from top to bottom in a group in the periodic table?

Back

It decreases

Front

If an electron is closer to the nucleus, it will be (harder, easier) to remove that electron and its ionization energy will be (high, low )

Back

Harder, High
