Q: Which of the following statements about isotopes is true?
Solution:
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons.
Steps: 5
Show Steps
Step 1: Understand that an atom is made up of protons, neutrons, and electrons.
Step 2: Know that the number of protons in an atom determines what element it is.
Step 3: Realize that isotopes are different forms of the same element.
Step 4: Remember that isotopes have the same number of protons but different numbers of neutrons.
Step 5: Conclude that this difference in neutrons gives isotopes different atomic masses.
