Different compounds have different numbers of constituent elements. here is no set number.

Generally HBr is hydrobromic acid which is formed due to the electrovalent or ionic bond between the ions of hydrogen and bromine.
Probably, thhere are three elements hydrogen, phosphorus and oxygen
Specifically, there are 3 hydrogen (H) atoms, 1 phosphorus (P) atom, and 4 oxygen (O) atoms.
88 different elements exist in nature.
That depends entirely on the concentration of H3PO4 dissolved in the solvent. It can have many different values of pH ranging from below zero at high concentration to near 7 at very low concentration.
Sodium and chlorine combine to make the most common salt, sodium chloride. It should be noted though, that many different elements can combine to make many different salts.

There are currently 117 different elements known to humankind. Those elements make up everything we know.
There is one phosphorus atom in the chemical formula H3PO4.
One molecule of glucose is composed of three different elements: carbon, hydrogen, and oxygen.
There are four oxygen atoms in one molecule of H3PO4.
No. Elements are make up of only one type of atom, rocks are made up of many different elements.
There are three different elements, carbon, hydrogen and oxygen.
