Question

find out numbar of protons electorons and neutrons in the nuclide 18 ar 40
​

Answer 1

Answer:

18 protons,  18  electrons, and  22  neutrons.

Explanation:

In the form of an element,  Y Z X ,  Z  is the number of protons, and also the number of electrons, and  Y  is the atomic mass.

So, in the case of  40 18 Ar , then it has  18  protons and  18  electrons.

The number of neutrons is given by subtracting the atomic mass from the proton number. So here,  Y = 40 , and the number of neutrons is: Y − Z = 40 − 18 = 22
