    An isotope refers to two or more forms of a specific element that has the same number of protons but an unequal number of neutrons. Moreover, if the element is neutral, the number of protons is equal to the number of electrons. For this question, the atomic structures of Li-6 and Li-7 b oth have 3 protons and 3 electrons, but Li-7 has 4 neutrons.
