What else can I help you with?
This is a pale yellow element that occurs widely in nature in several free and combined allotropic forms?
The element you are referring to is sulfur. It is a non-metal that is commonly found in nature in various forms, such as pure elemental sulfur, sulfides, and sulfates. Sulfur is known for its pale yellow color and distinctive odor.
In what form is copper found in nature?
Copper is commonly found in nature in the form of sulfide ores, such as chalcopyrite, bornite, and chalcocite. It can also be found in the form of oxides, carbonates, and native copper, which occurs as pure copper metal in its natural state.
How common is sulfur in nature?
Sulfur is fairly common in nature and is the 16th most abundant element in Earth's crust. It is found in various forms, including sulfide minerals, sulfates in rocks and minerals, and in organic compounds in living organisms. Sulfur is also present in the atmosphere as sulfur dioxide and hydrogen sulfide gases.
Almost all metals occur naturally in the state but they vary in?
physical and chemical properties. Some metals are found in pure elemental form, while others are typically found in ores that require processing to extract the metal. The abundance and distribution of metals in the Earth's crust also vary.
What is the last of the alkaline earth metals?
The last of the alkaline earth metals is radium. It is a highly radioactive element and is not found in its pure form in nature due to its instability. Radium was discovered by Marie Curie and Pierre Curie in 1898.
What form is uranium found in nature?
Today are known more than 200 uranium minerals: oxides, vanadates, hydroxides, phosphates, sulfates, carbonates, arseniates, silicates, molybdates, thucholites, selenides, tellurides, etc.
Why are neither theh alkali metals nor the alkaline-earth metals found uncombined in nature?
Due to their very high reactivity with oxygen and also water, they combine to form oxides, hydroxides and from there to carbonates and others.
Are alkali metals ever found uncombined in nature?
Alkali metals are very reactive and tend to form compounds with other elements. They are not found in their pure form in nature due to their high reactivity with moisture and air. Instead, they are typically found combined with other elements in minerals such as silicates, carbonates, and chlorides.
Are metallic carbonates basic in nature?
Yes, metallic carbonates are basic compounds. When they dissolve in water, they release hydroxide ions, which can react with acids to form salts and water.
What forms of polyatomic ions occur in nature?
Some common polyatomic ions that occur in nature include sulfate (SO4^2-), nitrate (NO3^-), carbonate (CO3^2-), and ammonium (NH4^+). These ions are often found in minerals, salts, and organic compounds in the environment.
What is a problem in nature of acids reacting with carbonates?
After this reaction carbon dioxide is evolved.
Common carbonates and carbonates symbols?
Strontium carbonate (SrCO3) is the carbonate salt of strontium that has the appearance of a white or grey powder. It occurs in nature as the mineral strontianite.
What is the meaning of nature in nature of metals?
the properties or description of metals. that's it!
What are the relationships between transitional metals?
transitional metals all either have one or two valence electrons, are all solids(excluding mercury), and are usually found combined in nature
Why group 2A are called the alkali earth metals?
The name "Alkali" is given due to the alkaline nature of their oxides and hydroxides. The term "Alkali Earth Metals" is used as these metals are usually found as minerals in the Earth's crust.
Are metals non metals or metalloids dull or shiny?
metals are malleable in nature
Are alkali metals always found pure in nature?
Alkali metals are not found as pure elements in nature.
