Calculate the number e, p, n for elements with ordinal numbers 17,23,52,83.

Explanation of the solution to the problem: the number of electrons in an atom is equal to the number of protons in the nucleus, and they are equal to the charge of the atom, that is, the ordinal number of the element, and the number of neutrons is calculated by the following formula:
n = A – Z, where n is the number of neutrons in the atom, A is the atomic mass, Z is the charge (ordinal number).
Solution:
17 is chlorine: e = 17, p = 17, n = 35 – 17 = 18.
23 is vanadium: e = 23, p = 23, n = 51 – 23 = 28.
52 is tellurium: e = 52, p = 52, n = 128 – 52 = 76.
83 is bismuth: e = 83, p = 83, n = 209 – 83 = 126.
