positive ion - magnesium(cation) negative ion-chloride (anion)
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.
Because for every Mg2+ ion there are two Cl- ions and so the charges balance each other out.
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.
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 would be two chloride ions present in a formula unit of magnesium chloride, as magnesium has a 2+ charge and chloride has a 1- charge. The charges must balance out in the formula unit.
positive ion - magnesium(cation) negative ion-chloride (anion)
Magnesium ions (Mg^2+) get their charge by losing two electrons from their outer shell, resulting in a positive charge of +2. This happens when a magnesium atom undergoes oxidation to form an ion.
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.
Magnesium carbonate, MgCO3, is an ionic compound containing magnesium ions, Mg2+, each with a 2+ charge and carbonate ions, (CO3)2-, each with a 2- charge. However, the bonding between the carbon and oxygen atoms in the (CO3)2- ion is covalent, and coordinate covalent (dative).
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.
You would need one magnesium ion (Mg^2+) and two oxygen ions (O^2-) to form an electrically neutral compound like magnesium oxide (MgO). The 2+ charge on the magnesium ion balances the 2- charge of the two oxygen ions, resulting in a neutral compound.
No: Each "mole", more precisely called "formula mass", of sodium chloride contains two ions, as shown by its formula NaCl, but each formula mass of magnesium chloride has three ions as shown by its formula MgCl2. This is true because sodium cations have only one positive electric charge unit, magnesium cations have two electric charge units, and chloride ions have one negative electric charge unit each.
I would expect the ions in a sample of magnesium fluoride to have a strong attraction for each other because magnesium ions are typically doubly charged cations, and fluoride ions are typically singly charged anions. The strong electrostatic attraction between ions of opposite charge results in the formation of a stable ionic compound like magnesium fluoride.
