Why are elements rarely found as pure substances?

Answer 1

The Group 1 elements, the alkali metals, are so reactive that they have to be stored in oil; they will react explosively with water and since water is so prevalent in nature and the alkali metals are so unstable, you'd be very hard-pressed to find a naturally occurring sample. I urge you to go on YouTube and look up reactions of Group 1 metals reacting with water. It's quite amusing.

Answer 2

Most of the elments are found as oxides and carbonates in the earths crust. The reason lies in the electropoositive nature of elements and high electronegativity of oxygen that they exist as compounds. The origin goes back to the evolution of earth when earth. However noble metals such as gold, platinum are found in pure form inside earth due to their low reactivity.

Answer 3

Several common elements are found in pure form in nature. These include:

• oxygen
  
• nitrogen
  
• copper
  
• gold
  
• silver
  
• carbon
  
• sulfur
  

Answer 4

Elements are rarely found as pure substances in nature because they tend to form compounds with other elements due to their tendency to bond and achieve a stable electron configuration. Additionally, environmental factors such as temperature, pressure, and the presence of other elements contribute to the formation of compounds rather than pure elements.

Answer 5

Most will combine chemically with other elements.

Answer 6

They are reactive and they found in the form of compounds

Answer 7

They are rarely found in nature.

Answer 8

In mixtures with other elements.
