2Br is two separate bromine atoms. Br2 is a bromine molecule, consisting of two bromine atoms bonded together.
This compound is the calcium iodide - CaI2.
There are two atoms of Bromine (Br) and one atom of Copper (Cu) in this compound. Thus, there are two elements, but three atoms.
Br is the chemical symbol for Bromine. There are three fluorine atoms covalently bonded, so they form triflouride. The full name is then bromine fluoride.
No. Starches are organically bonded carbohydrates, but calcium is an ionic compound with no hydrogen atoms.
You could never find these two elements alone in a compound... they'd have to be with something else (e.g - chlorine) then it would become Calcium Bromide.
2Br is two separate bromine atoms. Br2 is a bromine molecule, consisting of two bromine atoms bonded together.
Potassium and bromine form the ionic compound potassium bromide with the chemical formula KBr.
A compound, and it's name would be calcium oxide.
It would be nonpolar. But since it has two atoms of the same type it would be an element, not a compound.
Ca3N2, calcium nitride, containing Ca2+ and N3-
It is 1 calcium atom and 2 bromine atoms which totals 3 atoms
Calcium difluoride, CaF2 Dialuminium trisulphide, Al2S3
This compound is the calcium iodide - CaI2.
Calcium fluoride is CaF2, and aluminium sulfide is Al2S3. All numbers should be subscripts.
