Which of the following species correctly represented an ion of M with 13 protons and 10 electrons?
Answer Details
An ion is an atom or molecule that has lost or gained one or more electrons and has a net electric charge. In this question, the element M has 13 protons and 10 electrons, which means it has a net charge of +3 to balance out the charges of the protons and electrons. Therefore, the correct answer is 13M 3+. The other options are incorrect because they either have the wrong number of protons or the wrong number of electrons to match the given element.
