Comparison of Properties of Ionic and Covalent Compounds. Because of the nature of ionic and covalent bonds, the materials produced by those bonds tend to have quite different macroscopic properties.

Nitrogen is a chemical element with symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. The name nitrogène was suggested by French chemist Jean.
