Question

The atomic number of chlorine is 17 and its weight is 35 calculate the number of proton neutron and electron present in that atom​

Answer 1

Answer:

all are 17 Na proton, electron, neutron

Answer 2

Answer:  The number of protons  present in that atom​  :-  17  

               The number of neutron  present in that atom​ :-   18

               The number of electron  present in that atom​  :-  17        

Explanation:Since , The Atomic Number(Z) of an Element is equals to the number protons in the nucleus of its atom.  So , in a neutral atom

  Atomic number of the element = No of protons or No of electrons

Likewise the Mass Number is the sum of total number of protons and neutrons present in the nucleus of an atom .

Mass Number (M) =  No of protons(Atomic Number) + No of Neutrons

No of Neutrons =  Mass Number(M) - Atomic Number (Z)
