To Explain: If larger
Answer to Problem 1CQ
The larger atomic mass does not mean greater atomic number.
Explanation of Solution
Consider the expression for atomic mass.
Here,
Observe that atomic mass is the sum of the number protons and neutrons. If atom A has greater atomic mass than atom B, it depends on both no. of protons and neutrons. Consider the isotopes. They all have the same atomic number but different atomic masses.
Conclusion:
Hence, larger atomic mass does not mean greater atomic number.
