Question

question① select the correct answer. a typical atom is made up of neutrons, protons, and electrons. the atomic mass is calculated by adding the total number of neutrons and the protons. how would an element have a different atomic mass? answer by having different number of neutrophils by having different number of protons by having different number of electrons by having different number of neutrons i dont know yet

Explanation:

Atomic mass is sum of neutrons and protons. Protons define the element. Changing number of electrons doesn't affect mass much. Neutrophils are cells in biology, not related here. So different number of neutrons (isotopes) gives different atomic mass for an element.

Answer:

By having different number of neutrons
