Answer

Explanation:

Question 36

Step1: Determine the electron configuration of chlorine

Chlorine has an atomic number of 17. Its electron configuration is (1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}). The highest occupied energy level is the third energy level ((n = 3)).

Step2: Count electrons in the highest energy level

In the third energy level ((3s^{2}3p^{5})), the number of electrons is (2 + 5=7).

Question 37

Step1: Determine the electron configuration of strontium

Strontium has an atomic number of 38. Its electron configuration is (1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}). The highest occupied energy level is the fifth energy level ((n = 5)).

Step2: Count electrons in the highest energy level

In the fifth energy level ((5s^{2})), the number of electrons is (2).

Question 38

Step1: Determine the electron configuration of copper

Copper has an atomic number of 29. Its electron configuration is (1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{1}3d^{10}). The highest occupied energy level is the fourth energy level ((n = 4)).

Step2: Count electrons in the highest energy level

In the fourth energy level ((4s^{1})), the number of electrons is (1).

Question 39

Step1: Recall the group - electron relationship

For main - group elements, the group number (for groups 1A - 8A) gives the number of valence electrons (electrons in the highest occupied energy level). Group 5A elements have 5 valence electrons.
