Name an element which is octa atomic

Witryna30 sty 2024 · Wikipedia. The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule, … WitrynaThe recommendations are mostly ignored among scientists, who simply call these elements by their atomic number, for example "element 119" (instead of "ununennium"), with the symbol of (119) ...
