POF₃
Further explanation
A certain compound is made up of one phosphorus (P) atom, three fluorine (F) atoms, and one oxygen (O) atom.
Question:
What is the chemical formula of this compound?
The process:
The chemical formula of a compound states the type and the relative number of atoms contained in the substance.
- Element symbols are written with capital letters, in this case, P, O, and F.
- But if in other cases, these elements, for example, sodium or iron, the first letter is capital while the second letter is lowercase. Here is the writing: [tex]\boxed{ \ sodium = Na; \ iron = Fe \ }[/tex]
- We can add the number of atoms present as a subscript and it applies to three fluorines.
As follows, the chemical formula of this compound is [tex]\boxed{\boxed{ \ POF_3 \ }}[/tex]
The names of these compounds are as follows:
- Phosphoric trifluoride
- Phosphoryl fluoride
- Phosphorus oxyfluoride
Notes:
- POF₃ is a colorless and similar gas to POCl₃ or POBr₃. Remember that F, Cl, Br are included in the halogen group.
- The molecular shape of POF₃ is tetrahedral with a bond angle of 103°.
