find the number of neutron electron and proton in the nuclide 18.Ar40​

Sagot :

Answer: The number of neutron electron and proton in the nuclide [tex]_{18}^{40}\textrm {Ar}[/tex] is 22, 18 and 18.

Explanation:

Atomic number is equal to the number of protons or number of electrons for a neutral species and is specific to a particular element.

Mass number is the sum of number of protons and the number of neutrons.

Here the atomic number of Argon is 18 , thus the number of protons is 18 and thus the number of electrons is also 18.

The given mass number is 40. Thus number of neutrons = (40 - 18) = 22.

The number of neutron electron and proton in the nuclide [tex]_{18}^{40}\textrm {Ar}[/tex] is 22, 18 and 18.
