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.
Sulfur. It has six valence electrons. These six electrons plus the ten core electrons, 16, the atomic number (number of electrons or the number of protons [they are an equal amount because the positive and negative charges have to cancel each other out]). It is sulfur.
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.
Argon has 18 core electrons. This is because the atomic number of argon is 18, and the number of core electrons is equal to the number of electrons in the nearest noble gas configuration, which in this case is neon (10 core electrons), plus the number of electrons in the next energy level, which is 8 for argon.

The Mg2 plus cation has 10 electrons.
The number of electrons is 10.
Yes, gallium typically has an oxidation number of +3. Gallium, when it forms compounds, tends to lose its three outer electrons to achieve a stable electron configuration.
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.

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).
