Question

question 2. how are the isotopes of a particular element alike? how are they different?

Explanation:

Isotopes of an element have the same number of protons (atomic number), which makes them chemically alike as the number of protons determines the element's chemical properties. They differ in the number of neutrons, leading to different atomic masses.

Answer:

Alike: They have the same number of protons and thus the same chemical properties. Different: They have different numbers of neutrons and different atomic masses.
