WebSep 15, 2024 · However, it was found that atoms of the same element can have different numbers of neutrons. Atoms of the same element (i.e., same atomic number, Z) that have different numbers of neutrons are called isotopes. For example, 99% of the carbon atoms on Earth have 6 neutrons and 6 protons in their nuclei; about 1% of the carbon atoms have … WebThe isotope of an element can be defined as one of the several variants of the specific chemical element which holds the same number of protons and electrons as the atomic number of the element but holds a different number of neutrons when compared to the other variants (isotopes) of the element. Alternately, isotopes can be defined as variants ...

WebThe number of protons determines an element's atomic number (Z) and distinguishes one element from another. For example, carbon's atomic number (Z) is 6 because it has 6 protons. The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons.
