We are also told that this particular atom lacks 3 electrons instead of the usual one electron per proton, so it has only 10 electrons leaving the given ion structure as described in the question. We know that the atomic number of vanadium is 23 and the atomic average mass number is about 51. Hence, the proton is expressed by H+. The atomic number of an element is equal to the number of protons and electrons in that element. The actual mass of the electron is 9.1085 1028g or 9.1093 1031kg. That is, the charge of an electron is equal to that of a proton but the opposite. The elements in the periodic table are arranged according to their atomic number. When an atom carries a negative or positive charge by accepting or rejecting electrons, it is called an ion. Heavy nuclei with an even number of protons and an even number of neutrons are (due to Pauli exclusion principle) very stable thanks to the occurrence of paired spin.
