This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
Alkali metals have 1 electron in their outer shell.
There is one electron on cobalts outer shell.
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
Hydrogen has one electron in its outer shell and typically needs one more electron to achieve a full outer shell, which would complete its valence shell with two electrons (like helium). Therefore, hydrogen would need one additional electron to have a full outer shell.
Nitrogen has 5 electrons in its outer shell, so there are 3 electron pairs in the outer shell of nitrogen.
Alkali metals have 1 electron in their outer shell.
There is one electron on cobalts outer shell.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.

The outer shell (N=4) of the copper element has 2 electrons.
Potassium has one electron on its outer shell. It belongs to group 1 of the periodic table, so it has one electron in its outermost shell.
None - the electron goes from sodium TO the chlorine.
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
no electron is present in the outer most shell of hydrogen ion
1 valence electron
