Chlorine has two stable isotopes, chlorine-35 and chlorine-37. The atomic number chlorine is 17. calculate the numbers of protons, electrons and neutrons each isotope has.

Explanation:

The given isotopes are:

     Chlorine - 35

     Chlorine - 37

Atomic number of chlorine  = 17  

Now we need to calculate the number of protons, electrons and neutrons of each isotope.

Protons are the positively charged particles in an atom

Electrons are the negatively charged particles.

 Neutrons do not carry any charges.

Isotopes are atoms of the same element with the same atomic number but different mass number due to their different number of neutrons.

 For;

    Cl - 35:  Atomic number  = 17, mass number  = 35

    Number of protons  = Mass number  - Atomic number

    Atomic number  = number of protons  = number of electrons

         Number of protons  = 17

         Number of electrons  = 17

        Number of neutrons  = 35 - 17  = 18

For Cl - 37

       Number of protons  = 17

        Number of electrons  = 17

       Number of neutrons  = 37  - 17  = 20

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
