Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. The aluminum ion has a 3+ charge, while the fluoride ion formed by fluorine has a 1 charge. What is the mass ratio of aluminum to oxygen in aluminum oxide? WebIonic Compounds Naming and Formula Writing. Name each ionic compound. Because these ions contain more than one atom, they are called polyatomic ions. However, it is not always true (for example, aluminum chloride, AlCl3, is not ionically-bonded as a pure compound, but does form ions when dissolved in water). Similarly, each calcium atom (group 2) can give up two electrons and transfer one to each of two chlorine atoms to form CaCl2, which is composed of Ca2+ and Cl ions in the ratio of one Ca2+ ion to two Cl ions. The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing polyatomic ions, and one specific, very important class of compounds known as acids (subsequent chapters in this text will focus on these compounds in great detail). Web( a ) Oxygen is in group VI (16), and so the charge is 6 - 8 = - 2 ( b ) Nitrogen is in group V (IS), and so the charge is 5 - 8 = -3.
