S and f metals
WebbThe alkali elements in the s-block consist of a single valence electron in their outermost shell. This outermost electron is loosely held which makes these metals highly … This sub-section deals with the formation of periodic table elemental metals since these form the basis of metallic materials, as defined in this article. Metals up to the vicinity of iron (in the periodic table) are largely made via stellar nucleosynthesis. In this process, lighter elements from hydrogen to silicon undergo successive fusion reactions inside stars, releasing light and heat and f…
