The chemical symbols for 10 different atomic cations with 10 electrons are: Ne, Na⁺, Mg²⁺, Al³⁺
Further explanation
In an atom there are levels of energy in the skin and sub skin.
This energy level is expressed in the form of electron configurations.
Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub skins in the skin of an atom, namely s, p, d and f. The maximum number of electrons for each sub skin is
s: 2 electrons
p: 6 electrons
d: 10 electrons and
f: 14 electrons
Charging electrons in the sub skin uses the following sequence:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.
Each sub-skin also has an orbital depicted in the form of a square in which there are electrons symbolized by half arrows.
An atom or cation that has 10 electrons means having an electron configuration as follows:
1s², 2s², 2p⁶
Judging from this configuration, the elements are in period 2 and group 8A
So the elements that meet are Ne
Whereas cations that meet 10 electrons are elements that release electrons so that they correspond to the electron configuration of the element Ne
and this element is located in period 3
This element is:
Na: [Ne] 3s¹
Na releases 1 electron into Na⁺ so that it matches the electron Ne configuration
Mg: [Ne] 3s²
Mg releases 2 electrons into Mg²⁺ so that it matches the electron Ne configuration
Al: [Ne] 3s² 3p1¹
Al releases 3 electrons into Al³⁺ so that it matches the electron Ne configuration
