The above statement is true.
Five elements make up group 16 of the modern periodic table: oxygen, sulphur, selenium, tellurium, and polonium. Because several of the elements in this group may be recovered from sulphide or oxide ores, they are frequently referred to as chalcogens or ore-forming elements. The valence shells of all chalcogens contain a total of 6 electrons. It is known that numerous chalcogens can exist in various allotropes. For instance, it is known that there are over 20 allotropes of sulphur and a total of 9 allotropes of oxygen.
