Sulfide ion is S2- ion
it is formed from the element sulfur gains two electrons.
Sulfur belongs to group 16, period 3.
The most common charge of magnesium is +2.
Chlorine is the member of the halogens family; the electrical charge of the chloride ion (Cl-) is -1.
Because the elements are grouped according to similar characteristics. Even by knowing where an element is on the periodic table based solely on its proton number, we can still predict its properties by using its position on the periodic table.
To determine the ionic charge of alkali metals, alkaline earth metals, and aluminum using the periodic table, locate these elements in their respective groups. Alkali metals (Group 1) have a consistent charge of +1, while alkaline earth metals (Group 2) have a charge of +2. Aluminum, found in Group 13, typically has a charge of +3. This pattern helps in quickly recalling their common ionic charges based on their group placements.
In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages ​​and that was a textbook for many years.
Transition metals are difficult to predict the most probable ionic charge using the periodic table because they can exhibit multiple oxidation states due to their partially filled d-orbitals. The transition metals are known for forming complex ions, and their variable oxidation states make predicting their charges challenging.
To determine the formula for lithium sulfide using the crisscross method, you would write the symbols for lithium (Li) and sulfide (S) with their charges. The lithium ion has a charge of +1, while the sulfide ion has a charge of -2. By crisscrossing the charges, you get Li2S as the formula for lithium sulfide.

The most common charge of magnesium is +2.
The correct formula for an ionic compound containing aluminum ions and sulfide ions is Al2S3. This formula results from the balance of charges between the 3+ charge of aluminum ions and the 2- charge of sulfide ions to form a neutral compound.
Ferrous Sulfide = Iron (III) Sulfide Both -> Fe2S3
Some elements in the periodic table have a nucleus that is surrounded by a cloud of electrons with a negative charge. This is one sentence using nucleus and periodic table.
Using mass spectrometer, one can identify and/or separate the isotopes of the elements and also predict its composition in a given mixture.
Phosphorus is number 15 on the Periodic Table of Elements. The most common charge is -3 because it needs three more electrons to fill it's outer shell.

"I predict, that, this is proper use of the word predict"
I predict that I will die, eventually.
