This is a compound, a molecule.
No, PH3 is not symmetric. The molecule has a pyramidal shape due to the lone pair on the central phosphorus atom. This asymmetry contributes to the overall molecular geometry of PH3.
due to the difference in the between the two atoms in the molecule
Nope, the bonds are covalent because phosphorus and hydrogen are both non-metals, and that's what happen when non-metals bond. Now, with that said, when you have a bunch of PH3 molecules together, there will be some hydrogen bonding between molecules, because PH3 is polar. It's polar because you have a difference in charge across the length of that molecule, which is a result of the hydrogens' 1 and only electron tied up in the covalent bond with phosphorus, meanwhile phosphorus has 1 electron pair unshared (see Lewis structures.) This means the positive end of one molecule will be attracted to the negative end of another molecule. This intermolecular attraction is called hydrogen bonding, and it explains many physical properties of polar substances which contain hydrogen.
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
Molecule I believe
A PH3 molecule contains 4 atoms: 1 phosphorus and 3 hydrogen.
No, PH3 is not symmetric. The molecule has a pyramidal shape due to the lone pair on the central phosphorus atom. This asymmetry contributes to the overall molecular geometry of PH3.
The valency of phosphorus in PH3 is 3, as it forms three covalent bonds with three hydrogen atoms in the molecule.
A PH3 molecule has a triangular pyramidal shape. The central atom is the Phosphorus atom, which is connected to three Hydrogen atoms.

P3+
due to the difference in the between the two atoms in the molecule
If it is PH3 then it is Phosphine , hydride of element Phosphorus and if it is Ph3 then it is short way to write the phenyl group (C6H5-) but it means three phenyl rings are attached to any trivalent atom as phosphorus, P(Ph)3
it tells you how much of the molecule the element is
The atom of an element is smaller than a molecule.
