Which could represent the empirical and the formula of a given compound?
The empirical formula is representative for the chemical composition of a compound; the structural formula is representative for the spatial structure of the compound.
How do you know if a formula is an empirical formula?
An empirical formula has no data about the structure of a compound.
Is aluminium oxide mixture element or compound?
Yes. Aluminum nitrate is a compound with the formula Al(NO3)3
Aluminum or sulfur configuration ends in 3p1?
Two aluminum atoms and three sulfur atoms are combined in the compound aluminum sulfide (2 Al + 3 S = Al2S3).
What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
What is the name the elements combined in compound AI2O3?
Aluminum and oxygen. The first two letters in the compound are Al, not AI, so the compound aluminum chloride is written Al2O3. Al is the symbol for aluminum and O is the symbol for oxygen.
Does Aluminum exist by itself or does it have to be in a compound or molecule?
Aluminum is an element, composed of molecules, is on the periodic chart, does exist by itself AND can be combined to form compounds.
Write the correct formula for the ionic compound composed of aluminum and bromide?
Al3+ and Br- together make, AlBr3
What is the empirical formula for the compound X39Y13?
X3Y is the empirical formula
Is aluminum oxide an element?
No, aluminum oxide is not an element. Indeed, nothing called an "oxide" can be an element, as this term indicates that the substance is combined with oxygen and is therefore a compound, not an element.
Does aluminum naturally occur?
Aluminum is abundant in the earth's crust, however it does not occur by itself in nature. All of the aluminum in nature is found combined with another element or compound.
Which could represent the empirical and the formula of a given compound?

What is the empirical formula of the ionic compound that forms sodium and fluorine?
NaF is the empirical formula
What type of bond is formed in a covalent compound?
the only kind of bonding happens when an electronegative atom (such as aluminum) attracts the electrons of another atom and they combined and form a compound
