Magnesium has an outer electron structure of 3s2. It needs to lose both these to get to Neons electron structure and hence be stable. This would make it Mg2+ which is normal. To lose just one and thus have a charge of just positive one is energetically unfavorable - it does not gain anything in terms of stability.

Why the formula of magnesium chloride is MgCl2?
Magnesium chloride is an neutral ionic compound. In neutral ionic compounds, the positive charge of the cations must balance out the negative charge of the anions. In the case of magnesium chloride, magnesium is the cation with an ionic charge of +2 and chlorine is the anion with an ionic charge (each) of -1. Since two chlorine anions together have a charge of -2 total, they balance out the one magnesium cation with a charge of +2.

Does magnesium charges negatively?
Magnesium is an element with a +2 charge when it forms ionic compounds, not a negative one.
What is the charges for MgF2?
+3
Which is the cation in mgbr2?
In the compound MgBr₂, the cation is magnesium (Mg²⁺). Magnesium donates two electrons to achieve a stable electron configuration, resulting in a positive charge. The anions in this compound are bromide ions (Br⁻), which balance the charge of the cation. Thus, MgBr₂ is composed of one magnesium cation and two bromide anions.
What is the chemical formula for Magnesium Oxide?
the final formula of magnesium oxide is MgO.
Infer Magnesium and sodium atoms are about the same size How does the size of a magnesium ion with a 2 charge compare with that of a sodium ion with a single charge?
The sodium ion will be larger. Because magnesium has one more proton than sodium, its nuclei pull harder on the electrons, reducing the ion's radius. This means that the magnesium ion is smaller.
What effect will one positive charge haven on another positive charge?
"repulsion"
What is the name of 1 magnesium 2 bromine?
The compound consisting of one magnesium atom and two bromine atoms is called magnesium bromide. Its chemical formula is MgBr₂. Magnesium bromide is an ionic compound formed from magnesium, which has a +2 charge, and bromine, which has a -1 charge.
What is the charge on nu cleus of an atom?
Positive. One positive charge per proton.
Does sodium and magnesium form convalent chlorides?
No because they both are positively charged ions. Ionic bonds form between an ion with a positive charge and one with a negative charge (a metal and a nonmetal). This happens because opposite charges attract, and two positive charges won't bond together.
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.
