In most atoms, these are the electrons in the s and p sub-levels of the highest (numbered) energy level. For example, phosphorus (P) has the electron configuration: 1s 2 2s 2 2p 6 3s 2 3p 3, or [Ne] 3s 2 3p 3. Therefore, unlike valence electrons, core electrons play a secondary role in chemical bonding and reactions by screening the positive charge of the atomic nucleus from the valence electrons. The number of valence electrons of an element can be determined by the periodic table group of the element (see valence electron): For main group elements Valence shell The outer shell of the Atom is referred to as the Valence shell.
Cl [Ne] 3s23p5, 18. Ar [Ne ] Covalent bonding occurs by a sharing of valence electrons, rather than an Valence Electrons, The Covalent Bond, How Sharing Electrons Bonds Atoms Ga: [Ar] 4s2 3d10 4p1. The 4s Gallium therefore has three valence electrons. Start studying Valence Electrons.

Argon Ar[Ne]3s23p6core electrons: [Ne]valence electrons: 3S23P6electrons of an atom are divided into two ;that is core electrons and valence electrons.core electron are electrons that do not participate in boding.valence electrons are outer shell electrons that is associated with an atom and they participate in chemical bonding. 2020-07-24 · So valence electrons are those special electrons which are placed in the most exterior valence shell of an atom. And now the question is why they are special?
That's the ultra most manage level. 2007-04-29
In the given electronic configuration of argon, the electrons present in 1st shell and 2nd shell are the core electrons and the electrons present in 3rd shell are the valence electrons. That means, Number of core electrons = 2 + 2 + 6 = 10
So, it has 3 electron shells, and that will be its valence shell. In the third shell, it holds a total of 2 + 6 = 8 electrons, so it has 8 valence electrons. Answer verified by Toppr
