Helium has completely filled orbitals. hence it is chemically inert (non reactive) and is found in its pure elemental form.
Yes it can be found in nature in trace amounts in the atmosphere. This is because it is SO UNREACTIVE, it cant possibly be found in compounds.
Most elements are sufficiently reactive so it can not exist in elemental form.
Compounds, or minerals. The most common is the sodium chloride found in sea water. They are too reactive to be found as free elements.
AnswerAlkali metals are the most reactive metalsFrancium is the most reactive metal. This is as it has many layers, the last layer having only one electron, far away from the positive pull of the proton.
Alkali metals, such as sodium and potassium, are highly reactive and tend to combine quickly with other elements in nature to form compounds. This is because they have only one valence electron, which they easily lose to achieve a stable electron configuration. Therefore, it is rare to find pure alkali metals in their elemental form in nature.
helium does not from any compounds.
Phosphorus us found in nature, but in the form of phosphate compounds rather than in pure elemental form. This is because phosphorus is highly reactive and will readily react with oxygen in the air.
No. Phosphorus is reactive with oxygen, so it does not exist in elemental form in nature.
Yes it can be found in nature in trace amounts in the atmosphere. This is because it is SO UNREACTIVE, it cant possibly be found in compounds.
Sodium is to reactive to occur in its elemental form in nature. It will react rapidly with oxygen and nitrogen in air and will react violently with water. The only effective way of extracting sodium from its compounds is electrolysis.

All the chemical elements from group I and II are very reactive; it is impossible to found these elements in nature in elemental state.

In nature, titanium is always found as a compound, not as a pure metal. Titanium is highly reactive (although less reactive alloys can be made from it).
They both are highly reactive and are not found in nature in elemental state.
Under standard temperature and pressure, elemental fluorine is a yellowish gas. However, fluorine is exceedingly reactive, and thus in nature it is always found bound to other elements, commonly in salts as the fluoride ion (F-).
