Phosphorus, like all atoms, tries to achieve a full electron shell. For Phosphorus to achieve its full shell and obtain an electron configuration that is isoelectronic with Argon, it must gain 3 electrons. Therefore, Phosphorus forms a -3 anion.
Silicon is the only element with 18 protons, it form NO cations.
Cations are positive.
Cu3P is an ionic compound. Copper (Cu) typically forms cations with a charge of +2, while phosphorus (P) forms anions with a charge of -3. In Cu3P, the copper cations and phosphorus anions form an ionic bond due to the transfer of electrons.
Phosphorus in the PCl4+ cation uses sp3 hybrid orbitals. This hybridization allows phosphorus to form 4 sigma bonds with the chloride ions, resulting in a tetrahedral molecular geometry.

Phosphorus itself does not have a distinct odor. However, when it reacts with air, it can produce phosphorus oxides which may have a slightly garlic-like odor.
Salts produce (metallic) positive catIONS and negative anIONS (of non-metals)
In a flame test, different cations produce characteristic colored flames, allowing for identification of specific substances even if multiple cations are present. However, precise identification may be challenging if the cations produce similar colored flames that are difficult to distinguish. Additional tests or methods may be required for accurate identification.
Syria,Jordan, and Israel all produce phosphorus-minerals salt that contains the element of phosphorus
Metals react with acids to produce a salt and hydrogen gas.

The molcular weight of PCl3 is 30.97 + (35.45 X 3) = 137.32 The amount of P required to make 5.49 g (30.97 / 137.42) X 5.49 = 1.23g
