Hey mate!!!
As we move from Sulphur to Selenium, the atomic size increases and hence the strength of the M-M bond decreases. As a result, S-S bond is stronger than the Se-Se bond and consequently, S shows greater tendency for catenation than Selenium

Hey !!
As we move from S to Se, the atomic size increases and hence the strength of E ---- E bond decreases. Thus, S ---- S bond is much stronger than Se ---- Se bond. Consequently, S shows greater tendency for catenation than selenium.
Good luck !!
