They are all chemical elements in Group 16 of the periodic table.
The atomic number of each element (number of protons in an atom) is:
oxygen 8
sulfur 16
selenium 34
tellurium 52
One commonality is that they all can form oxyanions with oxygen.
All belong to the same group (or family) and will have the same number of valence electrons (six) and will have similar properties.
they have the same number of valence electrons which is 6

sodium is a metal; silicon is a semimetal (metalloid); helium and sulfur are non metals
strontium is not essential for living organisms. Sulfur is essential because all living things need it to survive. They also need sodium and selenium.

Selenium is more in common with Sulfur because they are in the same group. They have the same number of valence electrons and the only elements Selenium is related to is Sulfur and Tellurium. Anna C.
The non-metals in the Oxygen Family/Group are oxygen, sulfur, and selenium. The metalloids are arsenic and antimony.
There are many elements that are contained in seawater. Some examples include magnesium, sulfur, selenium, silicon, fluorine, sodium, and chlorine.

Samarium (Sm), Scandium (Sc), Seaborgium (Sg), Selenium (Se), Silicon (Si), Silver (Ag), Sodium (Na), Strontium (Sr) and Sulfur (S) are chemical elements. They begin with the letter S.
