WebAtoms of the same element that contain differing numbers of neutrons are called isotopes. This variation in neutron count alters the element's mass number but not its atomic number. As a ... for instance, is made up of three different isotopes: carbon-12 (12C), carbon-13 (13C), and carbon-14 (14C) (14C). The atomic number of each of these ... WebIsotopes are the variations of an atom that are still classified as belonging to the same element. All isotopes have the same number of protons in their nucleus but will differ in … A mass spectrum of an organic compound will usually contain a small peak of one mass unit greater than the apparent molecular ion peak (M) of the whole molecule. This is known as the M+1 peak and comes from the few molecules that contain a C atom in place of a C. A molecule containing one carbon atom will … See more Carbon-13 ( C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons. As one of the environmental isotopes, it makes up about 1.1% of all natural carbon on Earth.
