Question

write the ground state electronic configuration of an atom having atomic mass number 37 and number of neutrons 20.​

Answer 1

Answer: The ground state electronic configuration of an atom having atomic mass number 37 and number of neutrons 20 is $1s^22s^22p^63s^23p^5$

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.

$Cl:17:1s^22s^22p^63s^23p^5$
