Why is aluminum not found as a free element?
Aluminum is highly reactive and easily forms compounds with other elements in nature. It is commonly found in minerals such as bauxite, where it is bonded with other elements like oxygen. It is rare to find pure aluminum in its free elemental form due to its reactivity.
Which two elements occur in a nature as liquid?
Two elements that commonly occur in nature as liquids are mercury and bromine. Mercury is a naturally occurring liquid metal, while bromine is a non-metallic element that exists as a liquid at room temperature.
Why doesn't calcium occur free in nature?
Calcium is highly reactive in its atomic form. It has 2 valence electrons with a relatively low electronegativity. Therefore it is eager to give up those two electrons to give itself an octet by way of ionic bonding. Any atom or ion with a -2 charge (and they are EVERYWHERE) will be very anxious to bond with calcium.
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.
What is the oxidation state of group 13?
Group 16 on the periodic table has elements that form a -2 charge when they bond ionically with metals. This group contains the very common elements oxygen and sulfur. They are usually referred to simply as group 16, group 6A, the "oxygen group," or by their old-fashioned name, the chalcogens.
Why most elements not found in the free state in nature?
Most elements are sufficiently reactive so it can not exist in elemental form.
Is chlorine found in its elemental state or combined with other elements?
Chlorine is never found free in nature. It is always combined with another or other elements into compounds. Chlorine is highly reactive, and it wants to borrow an electron from just anything it can get close to. In general, it actually wants to "steal" that electron to form an ionic bond, and sodium chloride (NaCl), which is table salt, is one example of a common chlorine compound.
A widely distributed nonmetal which is never found in its free elemental state?
There are many nonmetals that are rarely found in their elemental form naturally. One of the more widespread of these is chlorine. Because chlorine is so reactive, it is almost always present as compounds, such as sodium chloride.
Which metals occurs in a free state?
Only a few metals are found in the free state, generally metals react to form for example oxides, sulfides which then may further react. Some found free are gold silver copper and platinum. All of these are relatively unreactive
Does iron occur in the free state?
Iron does not occur in its free state in nature due to its high reactivity. It is typically found in minerals such as hematite, magnetite, and siderite, which must be processed to extract the elemental iron.
Does copper occur in free state?
Yes. copper is one of the elements that may, with luck, be found in the native state.
Element never found in its free state?
Fluorine is an element that is never found in its free state in nature due to its high reactivity, forming compounds with other elements very quickly.
What element is a widely distributed nonmetal never found in its free elemental state and is an essential component in all cell protoplasm DNA and various animal tissues and bones?
carbon
Why are most element not found in free state in nature?
most elements have partly filled orbitals (or shells) and they try to gain, lose or share electrons so as to satisfy octet rule. Hence they are reactive and not generally found in free state
Why is all compounds molecules?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
Is all molecules compound?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
Why is aluminum not found as a free element?
Aluminum is highly reactive and easily forms compounds with other elements in nature. It is commonly found in minerals such as bauxite, where it is bonded with other elements like oxygen. It is rare to find pure aluminum in its free elemental form due to its reactivity.
