Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, located along the staircase on the periodic table.

Front

What is the significance of the periodic table's groups?

Back

Elements in the same group have similar chemical properties due to having the same number of valence electrons.

Front

What is the trend in atomic radius across a period?

Back

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

Front

What is the trend in ionization energy down a group?

Back

Ionization energy generally decreases down a group as the distance between the nucleus and valence electrons increases.

Front

What is the trend in electronegativity across a period?

Back

Electronegativity increases from left to right across a period.
