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

Back

Atomic radius increases because you add more and more shells (energy levels).

Back

The atomic number is the number of protons in the nucleus of an atom.

Front

What is the significance of valence electrons?

Back

Valence electrons determine an element's chemical properties and reactivity.

Front

What is electronegativity?

Back

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

Front

What is the periodic trend for atomic size?

Back

Atomic size increases down a group and decreases across a period.
