Answer:
donates (loses) electrons
Step-by-step explanation:
Atoms are most stable when they have zero valence electrons (full octets) and have the same electron configuration as the Noble Gases.
Atoms that have 1-3 valence electrons are most likely to donate them to reach this stable configuration.
An example is Sodium (Na) has 1 valence electron, as it is group one of the periodic table, and it often forms as a positive cation (Na+1) by donating its valence electron.
