3 Fluorine atoms are required for 1 aluminum atom.
one to three
Calcium difluoride, CaF2 Dialuminium trisulphide, Al2S3
Calcium fluoride is CaF2, and aluminium sulfide is Al2S3. All numbers should be subscripts.
NaF, sodium fluoride
When atoms of two different elements chemically combine, they produce a compound. Such compounds include sodium chlorine, hydrogen fluorine, and barium sulfide. Note that if the elements are same, the result is a polyatomic element, not a compound.
Aluminum fluoride is AlF3. It has 3 fluorine atoms for each aluminum atom.
The fluorine. 2F - SrF2 ======the compound
one to three
Calcium difluoride, CaF2 Dialuminium trisulphide, Al2S3
Aluminum is an element. It is made entirely of aluminum atoms.
Calcium fluoride is CaF2, and aluminium sulfide is Al2S3. All numbers should be subscripts.
Two fluorine atoms can not form a compound they simply form a [molecule]
NaF, sodium fluoride
It would not be a compound. It is simply fluorine in its elemental form.
When atoms of two different elements chemically combine, they produce a compound. Such compounds include sodium chlorine, hydrogen fluorine, and barium sulfide. Note that if the elements are same, the result is a polyatomic element, not a compound.
When aluminum and bromine react, three bromine atoms combine with each aluminum atom.
The compound name of a sulfur atom and six fluorine atoms that share electrons is Sulfur hexafluoride.
