Question

1. as you change the number of neutrons in the carbon atom, you are creating isotopes of carbon. based upon your findings above, define isotopes. atoms of different elements that have different numbers of neutrons. atoms of the same element that have different numbers of electrons. atoms of the same element that have different numbers of neutrons. 0 / 1 submissions used

Explanation:

To define isotopes, we recall the key concept: Isotopes are atoms of the same element with different numbers of neutrons (since the number of protons defines the element, and changing neutrons while keeping protons the same gives isotopes). The first option is incorrect as it says "different elements", the second is incorrect as it refers to electrons. The third option matches the definition: "Atoms of the same element that have different numbers of neutrons."

Answer:

C. Atoms of the same element that have different numbers of neutrons. (Note: Assuming the third option is labeled C; if the original labels were different, adjust the label but keep the text. From the image, the third option text is "Atoms of the same element that have different numbers of neutrons.")
