F-1 (pretend the -1 is a superscript)
No. Fluorine is a chemical element. It will readily form fluoride ions.
OF2 is the formula for fluorine oxide.
Fluorine, the element has a symbol/"formula" F. As a charged ion it has a -1 charge = F- Otherwise, fluorine is a diatomic molecule= F2 Calcium is also an element with symbol/"formula" Ca. As an ion it has a +2 charge, so it can be written as Ca2+.
'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
The chemical formula for germanium is Ge, and for fluorine, it is F2.
The chemical formula for fluorine is F2 and for cesium it is Cs.
OF2 is the formula for fluorine oxide.
The chemical formula for fluorine tetraiodine is FI4.
The hydroxide ion's chemical formula is [OH]-
The Chemical Formula for Potassium Ion is K+.
The chemical symbol (not formula) of fluorine atom is F; the molecule is F2.
The chemical formula for fluorine gas is F2, which means two fluorine atoms are bonded together.
