Explanation:

Step1: Identify element information for Cl

For $^{37}_{17}Cl$, the atomic number (number of protons) is 17.

Step2: Calculate neutrons for Cl

The mass - number is 37. Neutrons = Mass - number - Protons. So, neutrons for Cl = 37 - 17=20.

Step3: Determine electrons for Cl

In a neutral atom, number of electrons = number of protons. So, total electrons in neutral Cl atom = 17.

Step4: Find valence electrons for Cl

Cl is in group 17 of the periodic table, so valence electrons = 7.

Step5: Identify element information for Xe

For Xe, the atomic number is 54, so number of protons = 54.

Step6: Calculate neutrons for Xe

The average atomic mass is approximately 131.293. For a common isotope, assume mass - number = 131. Neutrons = 131 - 54 = 77.

Step7: Determine electrons for Xe

In a neutral atom, number of electrons = number of protons. So, total electrons in neutral Xe atom = 54.

Step8: Find valence electrons for Xe

Xe is in group 18 of the periodic table, so valence electrons = 8.
