Periodic Trends

Front

What is the atomic radius?

Back

The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

Which trend describes the change in atomic radius across a period?

Back

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

Front

Which trend describes the change in atomic radius down a group?

Back

The atomic radius increases down a group because additional electron shells are added.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right across a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases down a group.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom.

Front

How does ionization energy change across a period?

Back

Ionization energy increases from left to right across a period.

Front

How does ionization energy change down a group?

Back

Ionization energy decreases down a group.
