Why does only carbon show catenation. ? Hydrogen, lithium, boron, beryllium also have very small size atoms even smaller than the carbon atom. But still, only carbon show catenation because it is able to create a very strong bond with other atoms. Why don't hydrogen, boron, beryllium, lithium creates such strong bonds since their atom's size is very very small ??
Catenation refers to the property of self–linking of atoms of an element. It depends upon bond energy, size, and bond length between the atoms of the same element. Thus, the element capable of forming stronger and self–linking bonds will have the best catenation property.
The examples of elements in which catenation takes place are:
-Carbon
-Boron
-Sulphur
-Silicon
Carbon is not the only one with catenation property. Silicon shows it to quite a good extent, sulphur and boron have also been shown to catenate. carbon has the highest degree of catenation because:
1. high C-C bond energy
2. tetravalency (large number of bonds)
3. small atomic size hence less diffused orbital
