Periodic Trends

Front

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

Back

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

Front

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

Back

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

Front

Define electronegativity.

Back

Electronegativity is the tendency of an atom to attract electrons when chemically combined with another element.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity in the periodic table.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases because electrons are further from the nucleus.

Front

What is the trend for ionization energy as you move across a period?

Back

Ionization energy increases as you move across a period from left to right.

Front

What is the trend for ionization energy as you move down a group?

Back

Ionization energy decreases as you move down a group.

Front

Define atomic radius.

Back

Atomic radius is a measure of the size of an atom, typically the distance from the nucleus to the outermost electron.
