Consider two different isotopes of the same neutral element.Which statements about these isotopes are true? (There may be more than one correct choice.)
A) Both isotopes contain the same number of neutrons.
B) Both isotopes contain the same number of protons.
C) Both isotopes contain the same number of nucleons.
D) Both isotopes contain the same number of orbital electrons.
E) The sum of the protons and neutrons is the same for both isotopes.

Question

Quizplus · Accepted Answer

Isotopes of an element have the same number of protons (defining the element) and the same number of electrons in their neutral state, ensuring they have the same chemical properties. The number of neutrons, and thus the total number of nucleons, can vary between isotopes, making choices A, C, and E incorrect.
