Provide information about the elements of Group $16$.

(N/A) Group $16$ of the periodic table consists of oxygen $(O)$,sulfur $(S)$,selenium $(Se)$,tellurium $(Te)$,polonium $(Po)$,and livermorium $(Lv)$.
These elements are collectively known as chalcogens. The term is derived from the Greek word for brass.
Oxygen is the most abundant element on Earth,accounting for approximately $46.6 \%$ of the Earth's crust by mass. Dry air contains $20.946 \%$ oxygen by volume.
Sulfur is found in the Earth's crust in $0.03-0.1 \%$ abundance. It occurs in combined forms as sulfates like gypsum $(CaSO_4 \cdot 2H_2O)$,epsom salt $(MgSO_4 \cdot 7H_2O)$,barite $(BaSO_4)$,and as sulfides like galena $(PbS)$,zinc blende $(ZnS)$,and copper pyrites $(CuFeS_2)$.
Trace amounts of sulfur are found in volcanic gases as hydrogen sulfide $(H_2S)$. Organic materials like eggs,proteins,garlic,onion,mustard,hair,and wool also contain sulfur.
Selenium and tellurium are found as metal selenides and tellurides in sulfide ores.
Polonium is a decay product of thorium and uranium minerals.
Livermorium is a synthetic radioactive element with symbol $Lv$,atomic number $116$,atomic mass $292$,and electronic configuration $[Rn] 5f^{14} 6d^{10} 7s^2 7p^4$. It has a very short half-life.
