Question

Q4. Define catenation. Why carbon has unique space in periodic table​

Answer 1

Required Answer:

☑Catenation is the ability of carbon to form long chains. In fact, carbon atoms are unique because of catenation—they are unique among all of the other atoms found in nature. Now, carbon chains are formed because they form bonds, or tetravalent bonds, with other carbon atoms. Carbon has two electron shells, with the first holding two electrons and the second holding four out of a possible eight spaces. Carbon's incredible ability to bond with many other elements is a major reason that it is crucial to almost all life.
