Thanks for ⦠It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state. For stable elements, there is usually a variety of stable isotopes. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers. In the case of Potassium the abbreviated electron configuration is [Ar] 4s1. The oxides of potassium react with water vigorously and with enough evolution of heat to cause boiling and spattering of hot caustic solution, [Chemical Safety Data Sheets SD-9, SD-10. eval(ez_write_tag([[250,250],'material_properties_org-banner-2','ezslot_1',111,'0','0']));report this adSince the number of electrons and their arrangement are responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements.
