Why do scientist need to identify ionic compounds?
Because Ionic bonds are the strongest of all in chemistry. If a compound is ionic, it is unstable and will most likely fix itself with a corresponding ionic compound.
What 2 element types form an ionic compound?
A metal (as positively charged cations) and a non-metal (as negatively charged anions) need to be held together to form an ionic compound.
What is the formula for the ionic compound rb and br?
Fe (III) has a charge of 3+. Br has a charge of 1-. This means that in order to make the overall charge of the ionic compound of Iron III and Bromine, there must be one atom of Iron III and three atoms of Bromine. This makes the formula FeBr3.
An ionic compound is a compound that consist of molecules made of atoms that are covalently bonded?
The given statement is not either true or false consistently. An ionic compound can contain atoms that are covalently bonded, as in sulfate and nitrate salts, but it need not contain any such covalently bonded atoms.
What is the ionic charge on the chromium ion in the ionic compound that has the formula Cr2O3?
The compound is Chromium(III) Oxide. Chromium is 3+, since the compound has to have a charge equal to 0. Since there is 2 chromium atoms each chromium atom must have a charge of 3+ to balance out the 3(2-) charges of each oxygen atom; 2x+3(-2)=0, transpose for x(chromium), (in case you need the working out).

Need the compound name for Sodium and Bromine?
Sodium Bromide - ionic compound - NaBr.
Is NaBrO3 molecular or ionic?
If a compound contains at least one metal atom and at least one nonmetal atom, the compound is ionic. Na (Sodium) is a metal. Br (Bromine) is a nonmetal. Therefore, the compound NaBr is ionic.

If you look at a compound how can you tell if its a covalent or an ionic bond?
You would need to know the chemical makeup of the compound. Ionic bonding occurs between a metal and a non-metal while covalent bonding occurs between non-metals
Is CaSO4 Ionic or covalent?
You cannot tell from a formula whether an compound is ionic or molecular. The distinction is arbitrary at best, and there are actually very few purely ionic compounds. Al2S3 will be somewhere between ionic and covalent. Depending what level you are at and wherer you are taught different classifications of aluminium sulfide are given. See link for one view. Al2S3 is a colorless high melting compound, the aluminium atoms are in tetrahedral coordination in the most stable forms. This is line with the size difference between S and Al. The electronegativity difference between Al and S is ony 0.97. These are factors that need to be taken into account when making a decision. My view is partially covalent partially ionic!
What information is needed to write a correct chemical to represent an ionic compound?
You need to know the charges on the positive and negative ions.
When determining the formula for a compound it is important to know the valence numbers of each element. Suppose you want to-write a formula for a compound with these two elements?
To be stable it would need to be A2B (2 of element A would give a total of 6 valence electrons + the 1 element B would give a total of 8 electrons in the covalent bond. The bond is now stable and you have a compound.)
