Question

Calculate the number of protons, electrons and neutrons in element X whose atomic number is 34 and mass number is 80​

Answer 1

Answer:
Given parameter -
We know that atomic number is the number of protons which is equal to the number of electrons present in an atom

And mass number is addition of the number of protons along with the number of neutrons known as nucleons as well

Explanation:

Atomic no of element X = 34
Therefore , no of protons = 34
Using the definition of Atomic number we derive that ,
No of protons = no of electrons = 34 (Ans )

Let number of neutrons be x

Now Mass Number = No.of protons + No of Neutrons
84 = 34 + x

Hence , x = 84 - 34
= 50 ( Ans )
