In the universe, neutrons are abundant, making up more than half of all visible matter. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac-colored flame.Ī neutron is one of the subatomic particles that make up matter. In general, potassium compounds are ionic and, owing to the high hydration energy of the K+ion, have excellent water solubility. ![]() All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a cation, which combines with anions to form salts. In the periodic table, the elements are listed in order of increasing atomic number Z.Įlectron configuration of Potassium is 4s1. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. The configuration of these electrons follows from the principles of quantum mechanics. Since the number of electrons and their arrangement are responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements. ![]() Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom. Therefore, the number of electrons in neutral atom of Potassium is 19. ![]() The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Potassium-41 is composed of 19 protons, 22 neutrons, and 19 electrons.
