How is this formula generated? What is the mass ratio of aluminum to oxygen in aluminum oxide? If possible, reduce the subscripts to give a ratio with the smallest whole numbers. Although both of these ions have higher charges than the ions in lithium bromide, they still balance each other in a one-to-one ratio. It has the same number of electrons as atoms of the next noble gas, krypton, and is symbolized Br. The simplest name, iron chloride, will, in this case, be ambiguous, as it does not distinguish between these two compounds. By convention, assume that there is only one atom if a subscript is not present. For example, if you see the formula \(\ce{Ba(NO3)2}\), you may recognize the NO3 part as the nitrate ion, \(\rm{NO_3^}\). Although it is convenient to think that \(\ce{NaCl}\) crystals are composed of individual \(\ce{NaCl}\) units, Figure \(\PageIndex{1}\) shows that no single ion is exclusively associated with any other single ion. The similarity may be more than mere coincidence; many scientists think that the first forms of life on Earth arose in the oceans. over here in Group Two, and Group Two elements, also Compounds are classified as ionic or molecular (covalent) on the basis of the bonds present in them.
