Notes: Periodic Trends

Atoms with fewer valence electrons are more likely to gain electrons, while atoms with more valence electrons are more likely to lose electrons.

Atoms with fewer valence electrons are more likely to lose electrons, while atoms with more valence electrons are more likely to gain electrons.

All atoms are equally likely to lose or gain electrons regardless of their valence electrons.

Atoms with a full set of valence electrons are the most reactive.
