All the elements of the group 4 family or carbon family exhibit the catenation property. The first member of this family contains the highest tendency to catenate.The tendency to catenate is given as follows:C > Si > Ge > Sn > PbThe tendency of catenation decreases down the group. This occurs due to the reason the atomic size increases down the group, and also, the strength of the covalent bond decreases. Thus, the catenation property gets decreased down the group.
