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.
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.
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.
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.
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.
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.
Magnesium typically forms ions with a +2 charge. This means it will lose two electrons to achieve a stable electronic configuration.
The compound magnesium phosphide, Mg3P2, consists of three magnesium (Mg) ions and two phosphide (P) ions. Each magnesium ion has a charge of +2, resulting in a total positive charge of +6 from the magnesium. Each phosphide ion has a charge of -3, giving a total negative charge of -6 from the two phosphide ions. Thus, the overall charge of Mg3P2 is neutral, balancing the +6 from magnesium with the -6 from phosphorus.
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.
MgCl2 is an ionic crystalline solid, with magnesium (Mg) ions carrying a 2+ charge and chloride (Cl) ions carrying a 1- charge. In this compound, magnesium ions are surrounded by 6 chloride ions and chloride ions are surrounded by 3 magnesium ions in a regular arrangement.
Magnesium is an element with a +2 charge when it forms ionic compounds, not a negative one.
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.
The formula for an ionic compound containing magnesium and chlorine is MgCl2. Magnesium has a +2 charge, while chlorine has a -1 charge, so two chlorine ions are needed to balance the charge of one magnesium ion.
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.
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.
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.
Two.
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.
