Let us now look into some of the basic properties of the ions. When two or more elements, both nonmetals /or a transitional metal and a nonmetal, are attached by covalent bonds the group is either a molecule or a polyatomic ion. Common Polyatomic Ions ; 1- 2- 3- 1+ 2+ acetate, CH 3 COO – . Ans. Ans. A cation is formed by removal of electrons from an atom therefore a cation contains less electrons than normal atom. Due to more protons than electrons,a cation has positive charge on it. In cases such as this, the ion with one more oxygen atom than the -ate anion is given a per- prefix. I really think this is useful for our study. In these cases, the difference between the ions is in the number of oxygen atoms present, while the overall charge is the same. For Ex:Ammonium ion,Carbonate ion,sulphate ion etc. Thus, a polyatomic ion is an ion that is composed of 2 or more atoms. Most of us have a first name, middle name (often not used), and last name.
