How Is the Atomic Number Related to Core Electrons
Valence Electrons Are the Electrons Orbiting the Nucleus in the Outermost Atomic Shell of an Atom. Electrons That Are Closer to the Nucleus Are in Filled...
How many core electrons and valence electrons are in Argon?
Argon is a noble gas with an electron configuration of [Ne]3s23p6 . 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.

How many core electrons does indium have?
(a) O: core electrons = 1s2, therefore there are two of them. (b) In: indium has three valence electrons and all the rest are core electrons. The core electrons include all the electrons in the energy levels below n = 5. (4d10 are core electrons since they are held in a lower energy level.)
