So, the alkali really wants to give one, and the halogens really want one, which is why they're so dangerous. For example, you wouldn't want any these reacting with fluorine because it has 7 electrons and really wants one more it's got the highest electrostatic force because of its high nuclear charge and lesser amt. This is why they're so dangerous because they can react easily with any element that doesn't have a full octet (complete set of valence electrons). potassium and all other elements in group 1a (alkali metals family) have. It is silvery-white in color, waxy, and soft. (calcium cesium nitrogen sulfur)Potassium is a chemical element with the symbol. You can't hold them all very easily, right? It's easy to drop one, which is why it's easy for them to donate 1 electron at STP. Potassium (atomic number 19, symbol K) is a metal and an important element in our diet. alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic tablenamely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). (Potassium compounds are also important to a lesser extent in the manufacture of explosives. Imagine that you're holding a bunch of books. potassium - Potassium - Compounds, Reactions, Elements: Of commercially produced potassium compounds, almost 95 percent of them are used in agriculture as fertilizer. Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).Īs you move down the column, the metals become more reactive because the nucleus gains more electrons and protons (more electron levels), weakening their electrostatic force.
