An atom of magnesium has '12' protons in its nucleus. '12+ '.

It also has '12' electrons in energy shells around the nucleus. '12-' . These 12 electrons are arranged as 2 electrons in the inner most shell to the nucleus, then 8 electrons in the next outer shell, and finally 2 electrons in the outermost shell.

For a magnesium atom to become a magnesium ion, it MUST lose 2 electrons. These two electrons are lost from the outer most energy shell, because they are furthest away from the nucleus.

So the charges are;_

Mg(atom ; 12+ & 12- = 0 (No charge)

Mg(ion) ; 12+ & 10- = 2+ (charge) because there are now 12 pluses compared to 10 minuses.

+12 - 10 = +2 (A little sum)

Hence the magnesium ion is described as 'Mg^(2+)'.

NB It is an atom when neutrally (0) charged

It is an ION when it carries any charge.

How many chloride ions are present in a formula unit of magnesium chloride?

In a formula unit of magnesium chloride (MgCl2), there are 2 chloride ions present. This is because magnesium has a +2 charge and chloride has a -1 charge, so it takes two chloride ions to balance the charge of one magnesium ion.


What does the formula for the compound magnesium chloride MgCl2 tell you about how many chloride ions are needed to cancel out the charge of magnesium?

The formula MgCl2 indicates that one magnesium ion (Mg2+) requires two chloride ions (2Cl-) to cancel out its charge. Each chloride ion carries a charge of -1, so two chloride ions are needed to balance the +2 charge of magnesium.


How many chloride ions are present in a formula unit of magnesium chloride given the charge of a mg ion is 2 plus?

There are two chloride ions present in a formula unit of magnesium chloride. This is because the magnesium ion has a 2+ charge, requiring two 1- chloride ions to balance the charge in a 1:2 ratio.


How many chloride ions are present in a formula unit of magnesium chloride given the charge on a mg ion is 2 plus?

Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.


What is the oxidation number of magnesium in MgO?

The oxidation number of magnesium in MgO is +2. Magnesium typically forms ions with a +2 charge, while oxygen typically forms ions with a -2 charge. In MgO, the overall charge of the compound is neutral, so the oxidation number of magnesium must be +2 to balance the -2 charge of oxygen.

What happens when a magnesium ion is attracted to a chlorine ion?

Magnesium ions have a +2 charge, while chlorine ions have a -1 charge. This results in an electrostatic attraction between the two ions, leading to the formation of an ionic bond. The magnesium ion and chlorine ion bond together to form magnesium chloride.


What is the charge of magnesium III fluoride?

The charge of magnesium (Mg) in magnesium III fluoride is +2, as it is a Group 2 element. The charge of fluoride (F) is -1, as it is in Group 17. As the compound is neutral, the 3 fluoride ions balance out the 3+ charge of the magnesium ion.
