The total number of electrons present in the valence shell Īs we know, the valence shell of an atom can be found from the highest number of principle quantum numbers which is expressed in the term of n, and in 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1, the highest value of n is 4 so that the valence shell of K is 4 s 1. Potassium electron configuration K (19) = 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 (completeĬonfiguration) or 4 s 1 (condensed configuration). Again two electrons in 3s and six in 3p and remaining one electron will go in 4s orbital. Orbital and the next six electrons will go in 2p orbital as P orbital can only Orbital can hold a maximum of two electrons only. The first two electrons will go in the 1s orbital as S The potassium atom has a total of 19 electrons, so we have to put 11Įlectrons in orbitals. Less) in any condition for a particular atom and may or not be equal to itsĮlectron configuration is the arrangement of electrons on the The valenceĮlectrons for a neutral atom is always definite, it cannot be varied (more or Valence electrons are the total number of electrons present You have to know what these two terms are, so without wasting your time let's goįor it, Difference between valence electrons and valency Know what valence electrons and valency of sodium are, aren’t you? But for this Potassium is not found in a free state in nature due to its high reactivity behavior so that it is abstracted from different compounds (mostly from salts).Īs we know how much potassium is being used in the world ofĬhemistry, so we must have very good proper information about its electronic properties to survive in the world of chemistry and that’s why you are here to Reactive alkali metals of group 1 with atomic number 11 in the periodic table. Potassium, a chemical element with a symbol K, is one of the highly
