Answer: The ground state electronic configuration of an atom having atomic mass number 37 and number of neutrons 20 is
Step-by-step explanation:
Atomic number is equal to the number of protons.
Mass number is the sum of number of neutrons and number of protons.
Mass number = number of neutrons + number of protons
37 = 20 + number of protons
number of protons = 17
The atomic number is specific to an element, and the element with atomic number 17 is chlorine.
Electronic configuration represents the total number of electrons that a neutral element contains.
