As a result, Zinc has a Valency of two(2). There, it loses two electrons in the outermost shell and forms a 2+. In order to achieve an octet, it has to gain six or otherwise lose two electrons. As Zinc has 30 electrons, which is 28 in the first three wheels and 2 in the fourth. The electronic configuration of Zinc is 1s 22s 22p 63s 23p 63d 104s 2.

The electronic configuration of Potassium is 2,8,8,1. Also, argon belongs to the group of noble gases and its valance shells are completely filled as they have no tendency to lose or gain electrons. The atom is stable as the outermost shell is complete, and the outer electron is 8. Valencies of Elements 15 to 19 15 P Phosphorus 5 4 3 2 1 0 -1 -2 -3 16 S Sulfur 6 5 4 3 2 1 0 -1 -2 17 Cl Chlorine 6 5 4 3 2 1 0 -1 -2 18 Ar Argon 0 19 K Potassium 1 -1 Valencies and Symbols of elements 15 to 19 that include Phosphorus, Sulfur, Chlorine, Argon, and Potassium Neon valency is zero because Neon is a noble, inert, and non-reactive gas. Due to this Neon is the least reactive and there is no true compound of Neon has been synthesized. As it is an inert gas and its electronic configuration is 1s2,2s2,2p6. Neon valency is 0, this is because it has completely filled the outermost shell as it is a noble gas. Valencies of Elements 10 to 14 10 Ne Neon 0 11 Na Sodium 1 -1 12 Mg Magnesium 2 13 Al Aluminium 3 1 14 Si Silicon 4 3 2 1 -1 -2 -4 Valencies and Symbols of element 10 to 14 that includes Neon, Sodium, Magnesium, Aluminum, and Silicon This is because it can bond in the outer orbitals 2p and 2s Nitrogen has either 3 or 5 Valence electrons. In order to achieve the noble gas configuration, carbon forms four covalent bonds and shares its valence electrons.Ĭarbon electron configuration will be 1s 22s 22p 2 The carbon atom contains 4 electronics in its outermost shell. Boron will lose 3 electrons rather than gain 5 electrons.

Then the valency = 8-n.Īs its valence shell has 2 electrons present for sharing. It has two electrons in its Valence shell and when the valence shell electrons are more than 4. Lithium li number of valence electrons is 1.īeryllium, its symbol is ‘ Be‘. To attain stability, Lithium needs to lose one electron. This is because the atomic number of lithium is 3 and electronic configuration = 2,1. As a result, it has no tendency to lose or gain electrons. Helium only has two electrons in its S-orbit. Hydrogen its symbol is ‘ H‘ has only one valence electron and can form only one bond with an atom that has an incomplete outer shell.
