Which observation supports the conclusion of constant nuclear density in different elements?.
- A.The energy levels of electrons vary significantly
- B.The size of the nucleus increases linearly with atomic number
- C.The density of nuclear matter remains similar across isotopes
- D.The number of protons determines the chemical properties
Model answer
What a good answer should say
- The density of nuclear matter remains similar across isotopes
Explanation
Why this works
The evidence shows that isotopes of the same element have similar nuclear densities despite differing numbers of neutrons. This implies that the fundamental structure of the nucleus does not change significantly with the addition of neutrons, leading to the conclusion that nuclear density is approximately constant.
