A certain ionic compound is made entirely of aluminum and oxygen.Chemical formulas indicate the ratios of the different types of atoms in a compound. Percentage composition indicates the relative masses of each element in a compound. Mass ratios are important for lab work, and atomic ratios are important for understanding chemical reactions.What is the formula for this compound?
Aluminium Oxide: Al2O3 The ions: Al3+ .............. O2- When they bond: It is ionic as it takes place by the transfer of electrons from Aluminium(metal) to Oxygen(Non-metal). Hence, the bond is: Al2O3, Aluminium Oxide or alumina.
some components might have extra effective than one available can charge. eg, Sodium, Na, is often Na+ (constructive can charge of one) yet Iron, Fe, might have numerous costs: Fe2+, Fe3+ in spite of the fact that this is the comparable element, each and each of those cations (surely charged ion) is distinctive, and each and each has distinctive impacts on ingredients in a reaction. (A reactant of Fe2+, will produce a distinctive product compound than Fe3+) so which you spot, that's significant to comprehend which cation is getting used interior the reaction (or you will possibly be able to type some thing which you relatively do no longer want, yet the two way your experimental effects would be thoroughly erroneous.) for this reason, we label the cations as Fe2+ or Fe(II), or Fe3+ or Fe(III).
