What does a Lewis electron-dot diagram for an atom of sulfur-33 look like? The orbital diagram for a ground-state oxygen atom is? What is the type of diagram that consists of the valence electrons surrounding the chemical symbol of the element?
An English physicist named J.J. Thomson discovered electrons in 1897. This discovery helped scientists to realize that atoms are made of even smaller bits. Unlike these earlier scientists, we can actually see atoms; just look at the photo of sulfur atoms up above! Seeing that picture would ...
What is the electronegativity of sulfur? What is the electronegativity of argon? What does electronegativity have to do with polarity? What is the electronegativity of silicon? What is the electronegativity of iodine? What is the electronegativity of potassium?
Does gold react with anything? Gold is one of the noblest—that is,least chemically reactive—of the transition elements. It is not attacked by oxygen or sulfur, although it will react readily with halogens or with solutions containing or generating chlorine, such as aqua regia. ...

these weren’t necessarily competing alternatives. The idea of an element, like that of an atom, had a rather varied connotation, and didn’t necessarily mean a primal type of matter. The three principles of Paracelsus, for example, were seen more as properties than ingredients: sulfur represen...
Sulfur had a less con- ventional Japanese name. Unlike other traditional non-metal elements such as boron, arsenic, phosphorus, and silicon where the traditional single-word kanji name was added a "素" (so, essence), sulfur kept its traditional kanji name " 硫黃" (iwo). Another noteworthy...
The S8 molecule is an octagonal ring of sulfur atoms. The crystal shown at the left is composed of an ordered array of these molecules. (This animation does not properly represent the actual vibrational motions of the molecule.) Compounds and molecules As we indicated above, a compound is...
What is one of the main differences between the phosphorus and sulfur cycles? What is a halide mineral? Which element has the same number of valence electrons as phosphorus? How many electrons does phosphorus have? How many s electrons does phosphorus have? What does einsteinium look like? Wha...
