Calcium is a highly reactive element that is important in strengthening bones. Which characteristic of Calcium makes it highly reactive?
Why does angry turtle want 8 valence electrons? 8 Valence electrons mean that the atom obeys the Octet Rule, and will be almost non-reactive. Only one group on the periodic table is almost non-reactive, the Noble Gases.The Noble Gases obey the Octet Rule because they have a full outer energy level with 8 valence electrons.That means every other element on the periodic table is reactive.The most reactive group of metals is Group 1, the Alkali Metals with 1 valence electron. The most reactive group of nonmetals is the halogens, Group 17, with 7 valence electrons.
