What group of elements is most likely to contain elements that will be found in pure nature
2 answers:
Answer: Option (D) is the correct answer.
Explanation:
Noble gases are the elements that have completely filled orbitals.
For example, electronic configuration of neon is .
Therefore, they do not react at ordinary conditions with any other element in the atmosphere.
Hence, they exist in pure form in the nature.
Thus, we can conclude that group of noble gases of elements is most likely to contain elements that will be found in pure nature.

Explanation:
A single displacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.
Synthesis reaction is defined as the reaction where substances combine in their elemental state to form a single compound.
Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.
Combustion is a type of chemical reaction in which hydrocarbons burn in the presence of oxygen to form carbon dioxide and water along with heat.
