They are too reactive to remain in a stand-alone form.

Active elements that never exist alone in nature are known as what?
diatomic
Do alkali metals tarnish?
Lithium, Sodium and potassium are all soft metals which can be cut easily with a knife. This freshly cut piece is a shiny silver color which tarnishes quickly to a dull grey as these metals react with the oxygen and water in air. Sodium tarnishes quicker than Lithium and potassium tarnishes quicker than sodium. Thus, Potassium tarnishes quicker than lithium and not the other way around.
Where is beryllium found in nature?
Beryllium is an alkaline earth metal and is not found alone in nature. It is typically found in combination with with other elements in minerals such as beryl and chrysoberyl. For more information, please see the Related Link below.
What is the definition of solitary nature?
Enjoyment of being alone.
Why does the group 7 elements not have many uses?
The answer to this question depends on which version of the periodic table you're referring to.According to IUPAC, Group 7 would consist of manganese (Mn), technetium (Tc), rhenium (Rh), and bohrium (Bh). This group does not have many uses because other than manganese, the others are either rare or synthetic. Manganese is used as an alloying material in steel and is crucial to Vitamin B1.If all of the transition metals are considered to be one group (or the old IUPAC/CAS method is used), then group 7 can refer to the halogens, or fluorine (F), chlorine (Cl), bromine (Br), Iodine (I), and Astatine (At). These elements are highly reactive and are famous for producing salts when combined with Group 1 or Alkali metals. These elements may not have many uses alone, but they have a crucial role in chemistry.
What element is never found in its pure state of nature?
I suppose that the question refers to chemical elements and their natural state. Indeed, some elements cannot be found "alone" (i.e., not combined) in natural state. This applies to the most reactive elements, such as fluorine (gas), chlorine (gas), sodium (alkali metal), etc.
Most reactive non metal element?
I would easily say that Fluorine is the most reactive element in the world. Fluorine is the most electronegative of all elements and will react with all elements. It is so reactive that it cannot be found alone in nature.
How many electron shells in bromine?
Bromine is a member of the halogen family of elements. Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals. Sodium bromide is a compound found in seawater. As with all reactive elements, bromine is never found alone in nature. It is always a part of a compound with other elements. Source: Chem4kids
What are the elements in Group IIA on the periodic table?
Group 2 (IIA) - Alkaline earth metals: Be, Mg, Ca, Sr, Ba, Ra ns2

Which group of elements is the most active and why?
The alkali metals, group one on the periodic table. Starts with Lithium (Li) and ends with Francium (Fr). Or at least until Ununnunium is discovered, as it will be thenext alkali metal. The reason for their high reactivity is that they have only one valence electron. Valence electrons are the electrons that are involved in forming bonds with other elements. With only one valence electron, the atomic radius (how far away from the nucleus electrons can travel) is at its largest, making it so much easier for the electron to be taken by an other element that needs one valence electron, such as Chlorine (Cl). The reason that it is hard to find pure Sodium (Na) in nature is because it is an alkali metal, and therefore tends to bond with other elements rather than be alone.
What are the different groups on the periodic table?
There are 18 groups in the modern periodic table. Elements in group 1 are also known as alkali metals. Elements in group 2 are also known as alkali earth metals. Elements in group 17 are also known as halogens (salt makers). Elements in group 18 are also known as noble gases.
Do alkali metals tarnish?
Lithium, Sodium and potassium are all soft metals which can be cut easily with a knife. This freshly cut piece is a shiny silver color which tarnishes quickly to a dull grey as these metals react with the oxygen and water in air. Sodium tarnishes quicker than Lithium and potassium tarnishes quicker than sodium. Thus, Potassium tarnishes quicker than lithium and not the other way around.
What does the science word metallic mean?
Metallic means that the substance contains some properties that belong to metals and some that belong to nonmetals. Metallic elements are located alone the "stairwell" shaped latter on the right side of the periodic table of elements.
Can nature alone give us comfort?

Where is copper found alone in nature?
In the ground. It is a metal that must be dug up and processed or purified to be of any use like gold or silver or zinc. They dig up metals like copper in Mines.
