consider the three isotopes of carbon. what do the three isotopes have in common? choose all that apply.\na they have the same atomic number.\nb they have the same number of protons.\nc they all have four valence electrons.\nd they have the same number of neutrons.\ne they have the same average atomic mass number.
Answer
Brief Explanations:
Isotopes are atoms of the same element with the same atomic number (number of protons). Carbon - 12, carbon - 13, and carbon - 14 are carbon isotopes. The atomic number of carbon is 6, so they all have 6 protons and 4 valence electrons. The number of neutrons varies among isotopes, and so does the atomic mass number.
Answer:
A. They have the same atomic number. B. They have the same number of protons. C. They all have four valence electrons.
