The number of protons in an isotope or an atom gives its atomic number whereas the number of protons and neutrons gives its mass number.

The Standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is estimated to be 4.44 ± 0.02 V at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential (E0) is declared to be zero volts only at 298.

Yes, we know that water is a universal solvent.

Water can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization.

Water is a polar molecule that has a high level of polarity and attraction to ions and other polar molecules.

Hence, all the above given options are the properties of water.
