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 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?
Two
The correct name for the compound MgCl3 is?
Mg has a +2 charge and Cl has a -1 charge.The correct formula is MgCl2
What does the 2 mean in CaCl2?
The number 2 in the formula for magnesium chloride stands for the fact that two chloride ions, each with a charge of -1, must be present in the compound for each magnesium cation, with a charge of +2.
What is the word equation for magnesium carbonate?
Formula for magnesium hydrogen carbonate is Mg(HCO3)2.

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?
Two
What is the formula for an ionic compound that contains the elements magnesium and chlorine?
Magnesium ions have a 2+ charge, while chloride ions each have 1- charge. In order to cancel out the charges to create a stable, neutral compound, the formula must be MgCl2.
The correct name for the compound MgCl3 is?
Mg has a +2 charge and Cl has a -1 charge.The correct formula is MgCl2
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 1 mole of sodium chloride and 1 mole of magnesium chloride has same number of ions?
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.

What is the number of ions in the element magnesium?
positive ion - magnesium(cation) negative ion-chloride (anion)
How many chloride ions are needed to cancel the 2 charge of magnesium in magnesium chloride (MgC12)?
Two.
What is the chemical equation for magnesium plus chlorine?
Magnesium has a charge of +2 and Chloride has a charge of -1. In order to make magnesium chloride have a net charge of zero, there must be twice as much of the chloride ion than the magnesium ion. The ratio of magnesium to chloride is therefore 1:2. With this knowledge, we can write the chemical equation MgCl2.
What is the formula and charge for Carbonate and Mg2?
The formula and charge for the carbonate ion is CO32- and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium carbonate, MgCO3.
What is the word equation for magnesium carbonate?
Formula for magnesium hydrogen carbonate is Mg(HCO3)2.
