What is the formula of cation or anion?

The positive ion, called a cation, is listed first in an ionic compound formula, followed by the negative ion, called an anion. A balanced formula has a neutral electrical charge or net charge of zero….Examples of Ionic Compounds.

How do you find the empirical formula from a cation and an anion?

To write the empirical formula for an ionic compound, we use the periodic table to identify the metallic cation and the nonmetallic anion and write their symbols and charges. We then determine the ratio of each element to ensure a total charge of zero.

What is the formula for Ag+ and Br?

Silver;bromide | AgBr – PubChem.

What is the formula for Al3+ and NO3?

What is the empirical formula of the compound formed by magnesium cation Al3+ and nitrate anion NO3- ? Two NO3- ions are needed to balance the charge of one Mg2+ . Thus, the formula is Mg(NO3)2.

How to make the chemical formulas for a merging cation and anion?

How to make the Chemical Formulas for a merging Cation and Anion? Basically, when a cation like Na (charge +1) and an anion like Cl (charge -1) combine, you get NaCl.. Same thing when Ca (charge +2) and O (charge -2) combine, you get CaO. But when. you combine Ca (charge +2) and Cl (charge -1) you get CaCl2, meaning two atoms of Cl.

Which is the correct formula for a cation?
