Chromium form three (not only two) bromides:
* CrBr2, containing 24,759 85 % chromium
* CrBr3, containing 17,991 45 % chromium
* CrBr4, containing 14,129 09 % chromium
1 gram of CrBr3 contain 179,91 45 mg chromium.

What is the charge of an ion that has an atomic number of 24 and contains 22 e?
The element with atomic number 24 is chromium, Cr. It therefore has 24 protons in the atom's nucleus. Since it only has 22 electrons, it has lost two electrons (to another atom), thereby incurring a double positive charge. The ion would be Cr2+ with charge +2.
IN Gelett Burgess essay bromides nd sulphiteswhat devices he used to differentiate between bromides and sulphites?
the writer gives the examples of division of human being into two broad classes of bromides and sulphites.becky sharp is an imaginative and emotional character of thakeray's novel "vanity fair".her ideas and behaviour are unusual and she is a sulphite.Amelia sedley is another character of "vanity fair".She is common in behaviour and thinking.She is bromide.So in politics,the president Franklin D.Roosvelt(in 1930s)of US was a sulphite due to his unusual and orignal policies.on the other hand the president Herbert Hoover(before roosvelt) of US was a bromide due to his common policies.So in literature,Bernard shaw was a sulphite and Merie carelli was a bromide.Lewis caroll who wrote "Alice in wonderland",was a sulphite because he had very unusual ideas.Samuel jhonson,a orose writer, was a bromide due to his common thinking.We may note that a writer like Lewis may be having bromidic private life.Though he is sulphitic in his art.It applies to all fields of kife,activities and thoughts.
Is a ruby a gem?
Yes, a ruby is a gemstone. It is a type of mineral called corundum, which is composed of aluminum and oxygen. Rubies get their red color from the presence of trace amounts of the element chromium.

They are often used in jewelry such as rings, necklaces, and earrings, and are considered one of the four precious gemstones along with diamonds, sapphires, and emeralds.
Is tungsten a renewable or non renewable resource?
Chalk is not renewable because it is spread thin once you write with it, making it impossible to get it back off the surface you wrote it on. There is almost no easy or cheap way to collect all the dust and put it back into another new piece of chalk. A good question for this would be: "HOW would you renew chalk?" Chalk is a biodegradable substance though.
What is the quantum number of americium?
1s: ↑↓ 2s: ↑↓ 2p: ↑↓, ↑↓, ↑↓ 3s: ↑↓ 3p: ↑↓, ↑↓, ↑↓ 3d: ↑ ↑ ↑ ↑ ↑ 4s: ↑ It's important to recognize from the above that chromium is an exception to the normal aufbau progression which would predict 1s2 2s2 2p6 3s2 3p6 4s2 3d4, which is to say that you would normally fill the 4s orbital completely with 2 electrons before starting on the 3d which would then have only 4. Copper is another such exception.
