(a)
Answer to Problem 29A
The number of protons=
The number of neutrons=
The number of electrons =
Explanation of Solution
The number of protons=
For the number of neutrons= Mass number − number of
The number of neutrons=
When the number of electron is equal to the number of protons, then atom is uncharged.
So the number of electrons =
(b)
Interpretation: The number of protons and neutrons are contained in the nucleus of
Concept Introduction :
The number of protons in an atom is called the atomic number. The sum of the number of protons and neutrons, is equal to the mass number. When the numbers of neutrons are different the mass number of element is changes but atomic number remains unchanged that consider as a isotope of the element.
