WebIf an electron is added an anion is formed. Of the eight most abundant elements in the Earth's crust only Oxygen forms anions; the rest form cations by loosing one or more electrons. When there are 8 outer most electrons in the s and p sub shells the atom has a tendency to resist change and ions are formed with great difficulty if at all. WebOxygen is the third most abundant element in the cosmos, after hydrogen and helium. Why would oxygen take the third spot when it is so heavy (relative to the five elements ignored for it)? It would seem logical to me that the third most abundant element would be lithium or beryllium as hydrogen and helium smash into each other. Share.
