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.
What elements have ions with a -3 charge?
IF by charge you mean form ions with a charge pf -3, then nitrogen forms nitrides containing the N3- ion and some phosphides contain the P3- ion. If you mean an oxidation number of -3 this is true for all of the elemnts in group 15.
What element is h2n?
The chemical H2N doesn't exist because it isn't properly balanced. Hydrogen (H) has a charge of 1+ while Nitrogen (N) has a charge of 3- In order for the formula to be true, it would need to be NH3 . Reason being, the three Hydrogen molecules have a total charge of 3+ which counteracts the Nitrogen's charge of 3+
Will MgF3 form based on the charge of their ions?
No: Magnesium forms divalent cations, while fluorine forms monovalent anions. The compound between these two elements will therefore have the formula MgF2.
Is there any formula CaHCO3?
The formula is not charge balanced. Meaning the Ca has a 2+ charge and the HCO3 has a net 1- charge. Thus, the formula is incorrect. If you remove the Hydrogen you make CO3 a 2- charged anion giving you CaHCO3 (Calcuim carbonate), or the Ca can bond with two HCO3 (hydrogen carbonate) anions to form Ca(HCO3)2 (Calcium bicarbonate)

How many electrons in a nitrogen ion?
The atomic number of nitrogen is 7. That means that nitrogen has 7 protons per atom, each one having a +1 charge. Assuming that the atom of nitrogen is electrically neutral, there must also be 7 electrons, each of them having a -1 charge, in order for the total charge of the atom to be 0.
What is the sum of the charges of all the cations and anions?
The sum of the charges of ions in an ionic bond is always equal to zero. The compound would consist of the minimum number of ions necessary to make the charge of the compound equal to zero.For example, the charge of Na is +1, and the charge of Cl is -1. When these are bonded in an ionic bond, the Na+ and Cl- make NaCl, with a charge of zero.When you have two elements that aren't equal in charge, then you must make it to where the charges of both the cations and the anions equal zero when summed. You do this by adding more cations and anions to the compound as necessary.For example, the charge of Magnesium is +2, and the charge of Nitrogen is -3. To make the charge of this compound equal zero, you would need three Magnesiums and two Nitrogens. (2+2+2-3-3=0.) This means that when Mg2+ and N3- are bonded in an ionic bond, they would make Mg3N2.But basically, the short answer is that the sum of the charges on the ions in a unit of a compound is zero.
What is the compound formula for Strontium Nitrate?
The chemical formula for strontium and nitrogen is Sr3N2.
How many elements and total does ammonia have?
It has total of two elements. They are nitrogen and hydrogen.
What is the formula for lead2 phosphate?
The formula for lead (II) phosphate is Pb3(PO4)2, because phosphate anions have a charge of minus three and lead (II) cations have a charge of plus two.
What elements have ions with a -3 charge?
IF by charge you mean form ions with a charge pf -3, then nitrogen forms nitrides containing the N3- ion and some phosphides contain the P3- ion. If you mean an oxidation number of -3 this is true for all of the elemnts in group 15.
What is the total number of atoms in the molecule N2O2?
Four, two nitrogen and two oxygen.
