The number of protons, electrons and neutrons are in an isotope of the element with an atomic number of 79 and a mass number of 200 is 79, 79 and 121 respectively.
What is atomic number?
Atomic number of an element is the number of protons in an atom of the element while the atomic mass is the sum of the protons and neutrons in the atom.
The electron number is equal to the number of protons in a neutral atom.
According to this question, the isotope of an element has an atomic number of 79 and a mass number of 200.
- Number of protons = 79
- Number of electrons = 79
- Number of neutrons = (200 - 79) = 121
Therefore, the number of protons, electrons and neutrons are in an isotope of the element with an atomic number of 79 and a mass number of 200 is 79, 79 and 121 respectively.
