How hany valance electrons are in the element potassium?
Valanceelectron
Ill tell you the method to find it out. First take the atomic number of potassium. Its 19. Now by Bohr's model the K shell can accommodate a maximum of 2, then 8 then 18 and so on. Now divide the 19 electrons among these shells so 2 in the first shell and 8 in the second shell.Now we have 9 more. So 8 more again in the 3rd shell (for accomplishing stability through the octet system) and then finally the last one on the last shell. So we have 1 valence shell electron.
Apart from this we have a more mordernized theory consisting of the orbital model of an atom which was developed thanks to quantum theory.
