Interpretation : The statement I and II are true or false is to be decided and check whether statement II is the explanation for statement I.

Concept Introduction : The mass number is the sum of the protons and neutrons in an atom.

Expert Solution & Answer

Answer to Problem 6STP

Statement I is false.

Statement II is true. The mass number of aluminum-27 is 27.

Explanation of Solution

The mass number is the sum of the protons and neutrons in an atom. The mass number of aluminum-27 is 27. Thus, the statement I is false.

Aluminum has an atomic number of 13. So, it will have 13 protons. The count for neutrons will be 14. Hence, the mass number will be 27.Statement II is true.

Conclusion

Thus, statement I is false, and statement II is true.
