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.

What is electronegativity?

Back

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