How do you predict the charges of ions formed by

Solution : Here, in the given problem we have to identify, which pair of atoms are iso topes of one another among the given pairs. So we first will see what is isotope and then we could discuss each pair and identify the i sotope pair. Isotopes are atoms with the same number of protons but have different number of neutrons. Since the atom ic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, we can also say that isotopes are elements with the same atomic number but d ifferent ass number. Now, we will check if the given pairs of ato
