negative charge
The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
Magnesium has 12 protons, so if there are only 10 electrons, then it will have a +2 charge.
Magnesium as an atom has two valance electrons. To complete it's octet, it must lose two electrons. Losing two electrons will make Mg have 12 protons and 10 electrons therefore having a +2 charge.
When magnesium loses its two electrons, it forms a magnesium ion with a charge of +2. This occurs because the neutral magnesium atom has 12 protons and 12 electrons, and losing two electrons results in a net positive charge. Therefore, the final charge of the magnesium ion is +2, represented as Mg²⁺.
negative
can depend charge depends on what other atom(s) it is bonded to in the molecule. if you were bonding 1 magnesium with 1 chlorine(magnesium chloride) then you would have a +1 charge magnesium ion.the variable is the type of bond and what it is bonded to
When a neutral magnesium atom loses two electrons, it becomes a magnesium ion (Mg²⁺). Since electrons carry a negative charge, losing two electrons results in a net positive charge of +2 on the magnesium ion. Therefore, the net electrical charge on a magnesium ion is +2.
If two electrons are removed from a magnesium atom, it would result in a +2 charge. Magnesium has 12 protons in its nucleus, so removing two electrons would leave it with 10 electrons, giving it a +2 charge as it now has more protons than electrons.
The symbol "24mg2" likely refers to the magnesium ion with a +2 charge. Magnesium has 12 electrons in a neutral atom, but since it has a +2 charge, it has lost 2 electrons, giving it 10 electrons in total when it becomes a Mg2+ ion.
Magnesium typically forms ions with a +2 charge. This means it will lose two electrons to achieve a stable electronic configuration.
This is the oxidation reaction of Magnesium, loosing two (negatively charged) electrons (2e-):Mg --> Mg2+ + 2e-So as you'll see Mg is 2+ charged
The neutral atom of magnesium has no electrical charge; the ion is bivalent.
