Webb4 nov. 2024 · Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell. WebbI sotope: A form of an element that has the same number of protons and a different number of neutrons Radioisotope: an unstable isotope of an element (radioactive isotope) Valence electrons: electrons in the outermost energy shell, if valence shell is full=inert, if valence shell is not full= reactive, atoms may give up or accept electrons to become … list of south african towns
