The chemical formula (not symbol) is NiBr2.
Formula: Ti3P4
The phosphide ion has a charge of 3-. Its symbol is P3-.
The formula (symbol) for aluminum is Al. The symbol for phosphorous is P. The formula for aluminum combined with phosphorous is AlP (aluminum phosphide).
The symbol of chromium is Cr. It has variable charges +2,+3. Its symbol along with its charges is Cr2+ or Cr3+.
Aluminum (or aluminium, if you're a Brit) phosphide.
Li3P it is an unstable solid the Lithium phosphide.
Iron phosphide may be one of the following compounds: (di-)Iron phosphide, Fe2P (tri-)Iron phosphide, Fe3P And to complete the picture, monoiron phosphide, FeP.
