Zero is always the sum of all charges in a formula for a neutral compound, whether ionic or not.
The sum of the masses of the atoms in an ionic compound is equal to the formula mass of the compound. It is calculated by adding the atomic masses of all the atoms present in the formula unit.
Lithium combines with sulphur to form lithium sulphide (Li2S)
NaBr is an ionic compound. Generally, a metal bonded with a nonmetal forms an ionic compound. Also, the difference in electronegativity between Na and Br is 2.03, which is definitely ionic.
No, salt is not always an ionic compound. It can be an ionic compound, like sodium chloride (NaCl), but it can also be a covalent compound, like sodium acetate (CH3COONa). The classification of salt as ionic or covalent depends on the elements involved and their bonding.
It is ionic, All the compounds of Sodium are ionic.
The sum of all charges in the formula for an ionic compound must be zero. This is because the compound is made up of positively and negatively charged ions that combine in such a way that the overall charge is neutral.
The sum of the masses of the atoms in an ionic compound is equal to the formula mass of the compound. It is calculated by adding the atomic masses of all the atoms present in the formula unit.

NaBr is an ionic compound. Generally, a metal bonded with a nonmetal forms an ionic compound. Also, the difference in electronegativity between Na and Br is 2.03, which is definitely ionic.
K2Cr2O7 is a formula unit because it represents the simplest whole-number ratio of ions in the compound potassium dichromate. Formula units are used for ionic compounds, while molecules are used for covalent compounds.
the sum of the atomic weights for all the atoms in the formula
MgO is an ionic compound and all the ionic compounds are represented by their emperical formula because actual no of atoms can not be represented due to a very huge crystal formation.(crystal lattice).
No, salt is not always an ionic compound. It can be an ionic compound, like sodium chloride (NaCl), but it can also be a covalent compound, like sodium acetate (CH3COONa). The classification of salt as ionic or covalent depends on the elements involved and their bonding.
It is ionic, All the compounds of Sodium are ionic.
No, It is ionic. All lithium compounds are ionic.
Sodium iodide is an ionic compound. It has chemical formula NaI and is made up of the ions Na+ and I-. These ions occupy alternate positions in a giant lattice structure and there are strong electrostatic forces of attraction between the oppositely charged ions.\
We use the term formula mass for ionic compounds because they do not exist as discrete molecules like covalent compounds. Instead, ionic compounds exist as a three-dimensional array of ions arranged in a crystal lattice. Therefore, the term formula mass better reflects the overall mass of the compound, considering all the atoms and ions present in its formula unit.
