how many protons and electrons are in a sodium ion?
435535
A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons.

The sodium atom is left with a full outermost electron shell with eight electrons, and the outermost shell of the other atom is full as well.

In an ammonium ion (NH+4) ion, there is one nitrogen atom and four hydrogen atoms. Nitrogen has an atomic number of 7 , and hydrogen has an atomic number of 1 , and so the total atomic number of the hydrogens will be 1⋅4=4 . So, there will be a total of 7+4=11 protons.

So, sodium's 11 electrons are arranged this way: 2 electrons in the first "shell", 8 electrons in the second "shell"; and 1 electron (the valence electron) in the third "shell". We write this as 2.8. 1. The last number is how we know the number of valence electrons.

Explanation: In an ammonium ion (NH+4) ion, there is one nitrogen atom and four hydrogen atoms. Nitrogen has an atomic number of 7 , and hydrogen has an atomic number of 1 , and so the total atomic number of the hydrogens will be 1⋅4=4 . So, there will be a total of 7+4=11 protons.

A potassium ion, K+ has an atomic number of 19 and a mass number of 39 So there are 19 protons and 39-19 = 20 neutrons. To become a positive ion it looses its valence electron with its valence shell and becomes K+ by achieving the configuration of 2,8,8,1 with 3 energy levels/shells.

Answer. There are 10 electrons present in Na+. The atom of sodium has 11 electrons, 11 protons along with 12 neutrons, but Na+ contains one less electron, 11 protons along with 12 neutrons, as the ion has lost 1 electron.

Potassium atoms have 19 electrons and 19 protons with one valence electron in the outer shell. Potassium is considered chemically similar to sodium, the alkali metal above it on the periodic table.

The sulfur has 16 electrons and 16 protons. But the ionic atom's electron quantity changes depending on how many it has gained. 'S2-' has gained 2 electrons, which means it has now 18 electrons and 16 protons.
