An atom of Hydrogen (H) has one electron (-1) and one proton (+1), and is uncharged (0).
H+ indicates that the Hydrogen atom has lost an election (-1) but still has the proton (+1) and thus has a positive charge (H+).
Because it only had one electron to begin with, when H becomes H+ it does not have any electrons left.
Therefore, H+ does not have any electrons.
The Mg2 plus cation has 10 electrons.
The number of electrons is 10.

A neutral aluminum atom has 3 electrons in its outer shell and a full outer shell of 8 electrons below that. This full outer shell is stable, so aluminum will lose its 3 outer shell electrons to achieve that configuration.
The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
3 electrons total. electrons is the number on the top right corner with the plus sign indicating that electrons are positive.
Sodium only has one electron in its outer energy level which it wants to lose in order to leave a stable octet of electrons in the level below. Loss of one electron causes a charge of plus 1 on the remaining ion.Magnesium has two electrons in its outer energy level, thus by losing these it takes on a charge of plus 2 and leaves a stable octet of electrons below in the next energy level.
The Mg2 plus cation has 10 electrons.
Hg will have 80 electrons.

For a neutral (uncharged) atom, the total number of electrons is equal to the atomic number (number of protons). This would be the sum of the core electrons plus the valence electrons.
Ions are formed when atoms gain or lose electrons in their outer orbit/shell. Electrons are negatively charged so if they lose an electron they become positively (plus) charged.
K is potassium, and it is found in group I and period 4. It is an s block element. So, being in group I, this indicates it has ONE electron in the outer shell (4s).
A neutral aluminum atom has 3 electrons in its outer shell and a full outer shell of 8 electrons below that. This full outer shell is stable, so aluminum will lose its 3 outer shell electrons to achieve that configuration.
