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.
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. Rubies are highly valued as gemstones for their intense red color and their rarity. 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.
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.
What are diamonds and emeralds are made of?
Diamonds are made of the element carbon. A perfect diamond contains nothing but carbon. Each carbon atom is tetrahedrally bonded to 4 other carbon atoms, making an very strongly 3-dimensional crystalline sructure.See the Web Links for more information about diamonds.
What element is Ar 3d1 4s2?
The element Ar 4s2 3d10 4p6 is Krypton (Kr).
Compound name for chromium bromide?
Another chemical name is chromium trichloride or chromic chloride. Chromium(III) chloride is a chemical name as well.
Is chrome related to chromium?
Yes. Chrome is just another name for the element chromium.
Why is chromium plated over another metal?
Chromium is plated over another metal to make it resistant to rust or corrosion.
Is chromium a element?
No, iron is an element. Chrmium is also an element, so there are no other substances, compounds or otherwise, that are found in it. However, there are alloys that contain both iron and chromium along with other metals.
What is a chemical reason for plating chromium onto certain automobile parts?
Chromium resists oxidation (rust). The steel parts need to be protected from the elements to prevent rusting. One way is to paint them. Another way is to protect them with something like chromium.
Is chromium a solid or liquid or a gas?
At what temperature? At 98 degrees Fahrenheit, it may be a solid, but at another temperature, it may be a liquid.
What part of speech is the word chrome in?
The word "chrome" can be a noun or a verb. As a noun, it refers to a type of metal with a shiny surface. As a verb, it means to plate or coat an object with chromium or a chromium compound to give it a shiny finish.
How is chromium made?
Chromium is typically obtained through the mining and extraction of chromite ore. The ore is processed to extract chromium by either using the traditional method of roasting and leaching, or modern techniques such as aluminothermic reaction or electrolysis. The extracted chromium is then further processed and refined to the desired form for use in various industries.
What are uses of chromium?
One major one is as alloy ingredient in stainless steel. another is chrome electroplate.
What are the benefits of chromium polynioctinate?
The benefits of chromium polynioctinate include controlling blood sugar levels in association with diabetic patients. Another benefit includes losing weight and gaining muscle thereby improving athletic performance.
What type of chemical bond is Chromium sulfate?
Chromium sulfate typically forms ionic bonds. In ionic bonding, one atom donates electrons to another atom, resulting in the formation of charged ions that are attracted to each other.
Can hexavalent chromium be generated from grinding?
I didn't think it was possible but apparently it is (from grinding stainless steel, that is). I guess if the chromium metal gets hot enough from the friction of the grinding wheel, then some of the chrome will convert to chrome 6. Below is a link. See Table 2. Also see the authors comment before Table 2: "Surprisingly the highest numbers are from arc-air, grinding and welding". The report doesn't give many details. it would have been nice to know if maybe these welders were working in an area with another possible source of chrome 6 such as welding.
