Question

Draw the electron-dot formula for sulfur. Include all of the valence electrons.

a) H
b) O
c) S
d) N

Answer 1

The electron-dot formula for sulfur, which has six valence electrons, includes two lone pairs and two single electrons, placed around the chemical symbol 'S' in the Lewis electron dot diagram.

Step-by-step explanation:

To draw the electron-dot formula for sulfur, you first need to know that sulfur has six valence electrons. The Lewis electron dot diagram for sulfur is constructed by placing dots representing these valence electrons around the chemical symbol for sulfur (S). Remember that the first four electrons are placed singly on each side of the chemical symbol, and any additional are paired up with the first four. For sulfur, which has the electron configuration [Ne]3s² 3p⁴, this would give us two lone pairs and two single electrons.

The Lewis symbol for sulfur would therefore look like this:

..S..

In this diagram, each dot represents a valence electron, and the dots are arranged so that there are two lone pairs (the pairs of dots) and two single electrons (the single dots).
