An element X has a mass number = 37 and it contains 17 protons.
(i) Write the symbolic representation of the element.
(ii) Find the number of neutrons and electrons in the element.
(iii) Write the electronic configuration of the element.
The mass number of the element X = 37
Number of protons = 17
(i) Symbolic representation is <ιμγωιδτη=∀27∀ηειγητ=∀25∀σρχ=∀Χη_4_φιλεσ/ιμαγε014.πνγ∀>
(ii) Number of neutrons = 37 – 17 = 20
Number of the electrons are = 17
(iii) Electronic configuration is 2, 8, 7
