How many protons neutrons and electrons are there in a neutral atom of 43k (potassium-43)?
Veronika [31]

Answer:

             Number of Protons  =  19

             Number of Neutrons  =  25

             Number of Electrons  =  19

Explanation:

Number of Protons:

                               The number of protons present in any atom are equal to the atomic number of that particular atom. Hence, as the atomic number of Potassium is 19 therefore, it contains 19 protons.

Number Neutrons:

                             The number of neutrons present in atom are calculated as,

                               # of Neutrons  =  Atomic Mass - # of protons

As given,

                                Atomic Mass  =  43

                                # of Protons  =  19

So,

                                # of Neutrons  =  43 - 19

                                # of Neutrons  =  24

Number of Electrons:

                                   As we know for a neutral atom the number of electrons are exactly equal to the number of protons present in its nucleus. So, for 19 protons in neutral Potassium atom there must be 19 electrons.
