Dictionary learning atoms
Webatom: [noun] the smallest particle of an element that can exist either alone or in combination. the atom considered as a source of vast potential constructive or destructive energy. WebThe basic answer is that atoms are trying to reach the most stable (lowest-energy) state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons).
