Q:

What is Lewis dot structure for sulfur?

A:

Quick Answer

The Lewis dot structure for sulfur includes the upper case letter S, the element's chemical symbol, surrounded by two sets of paired dots and two single dots evenly spaced around the letter. These dots represent the valance electrons sulfur has the potential to contribute when forming bonds.

The element's location on the periodic table shows the number of electrons to place around it in this type of diagram. Elements in group 1A have one dot while those in 2A have two dots and the pattern continues all the way to elements in group 8A, which has a total of eight electrons. The Lewis dot diagram for elements in group 8A, known as the noble gases, includes the atomic symbol surrounded with four sets of paired dots.

Sulfur forms covalent bonds with other elements by sharing unpaired electrons to form paired groups. For example, hydrogen, which has a valance shell with a potential for two electrons, has one electron in the outer shell. This allows two hydrogen atoms to share electrons with a single sulfur atom in the gas H2S. The Lewis structure of the compound adds one uppercase H next to each of the two unpaired electrons of sulfur, with an additional dot supplied by hydrogen to complete the pair.
