Answer:

1. The element with the atomic number 22 (symbol Mn) is the correct answer.

2. The element with the electron configuration ...3d³4s² is iron (Fe). So, the correct answer is D) Fe.

3. The electron configuration of a cobalt atom is ...3d⁷4s². So, the correct answer is D) ...4d⁵s².

4. The electron configuration 1s²2s²2p⁶3s²3p⁶4s² corresponds to calcium (Ca). So, the correct answer is A) Ca.

5. The p-block elements are: B) Al, Mg.

6. The electron configuration of Al is ...3s²3p¹. So, the correct answer is B) ...3s²3p.

7. The outermost shell electron count is equal to the period number. So, the correct answer is A) the period number.

8. The element with 14 more neutrons than protons is: C) P.

9. The element that does not have neutrons is: B) He.

10. The element 137Ba has 56 protons, 81 neutrons, and 56 electrons. So, the correct answer is C) 56p, 81n, 56e.

The descriptor for 56 is: 1) 1-5 = 48 points; 2) 6-8 = 60 points; 3) 9-12 = 65 points; 4) 13-14 = 70 points; 5) 15 = 80 points; 16 = 90 points.
