WebGroup 15 elements such as nitrogen have five valence electrons in the atomic Lewis symbol: one lone pair and three unpaired electrons. To obtain an octet, these atoms form three covalent bonds, as in NH 3 (ammonia). Oxygen and other atoms in group 16 obtain an octet by forming two covalent bonds: Double and Triple Bonds WebA chemical symbol: consists of one or two letters always starts with a capital letter, with any other letter in lower case For example, the element mercury is shown as Hg.

WebPolyatomic ions. In this article, we will discuss polyatomic ions. The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include \text {Na}^+ Na+, \text {Fe}^ {3+} Fe3+, \text {Cl}^- Cl−, and ...
