Periodic Table Trends

Front

What is the periodic trend for electronegativity?

Back

Electronegativity increases across a period from left to right and decreases down a group.

Front

What are alkali metals?

Back

Alkali metals are elements in Group 1 of the periodic table, known for being highly reactive and having one electron in their outermost shell.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

How does atomic radius change across a period?

Back

Atomic radius decreases across a period from left to right due to increased nuclear charge pulling electrons closer.

Front

What is the family name of Group 17 elements?

Back

The family name of Group 17 elements is Halogens.

Front

What happens to the atomic radius as you move down a group?

Back

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

Front

What is the trend for ionization energy down a group?

Back

Ionization energy decreases down a group because the outer electrons are further from the nucleus and are less tightly held.

Front

What is the relationship between electronegativity and ionization energy?

Back

Generally, elements with high electronegativity also have high ionization energy.

Front

What do atoms that form negative ions tend to do?

Back

Atoms that form negative ions tend to gain electrons.

Front

Which element has the largest atomic radius: potassium, rubidium, francium, or cesium?

Back

Francium has the largest atomic radius.
