Sulfur is famous for its distinctive smell. The production of black gunpowder, rubber, insecticides and many pharmaceuticals involves the use of sulfur.
Sulfur was used in the religious rites of many ancient cultures because its smell was thought to ward off evil spirits. Ancient Romans enjoyed fireworks displays and produced weapons which used sulfur.

The three parts of an atom are the protons, neutrons and electrons. Atoms make up the basic building blocks of matter and define the structure of elements. These parts were not officially identified until 1932.Full Answer >
Potassium has 19 protons, 20 neutrons and 19 electrons. The charges of the protons and electrons cancel each other out, so a neutral atom of potassium has a net charge of zero.Full Answer >
The Bohr model for nitrogen has a central nucleus with seven neutrons and seven protons, a first energy ring with two electrons and a second energy ring with five electrons. A more detailed version shows two electrons in the s sub-shell of the second energy ring and three electrons in the p sub-shell. The Bohr model is used to demonstrate how the electrons line up around the nucleus of an atom.Full Answer >
An atom is electrically neutral because it has the same number of electrons as it does protons. The atoms neutrality can only be changed by altering the number of electrons present in the atom.Full Answer >
