Discover the history, structure, and importance of the periodic table of elements, from Mendeleev’s discovery to modern scientific applications.

The most common defects in MoS 2 are instances of missing single sulfur atoms, also known as sulfur monovacancies. In a perfect sample, each sulfur atom has two valence electrons that bind to two ...

In addition, sulfur can also form four-coordinate 'hypervalent' bonds, where its formal number of valence electrons exceeds eight. Compounds containing these bonds are known as sulfuranes.

The iron-sulfur clusters in these DNA repair proteins are responsible for donating and accepting traveling electrons.

Metal sulfur coordination complexes are combinations of transition metals (one of 28 metallic elements, including iron and other common metals) surrounded by molecules or atoms that contain sulfur.

The iron-sulfur clusters in these DNA repair proteins are responsible for donating and accepting traveling electrons.

DNA primase accepts the electrons, becomes reduced, and lets go of the DNA. This donation and acceptance of electrons is done with the help of the iron-sulfur clusters.
