Interpretation:
The diagram that represents the arrangement of protons, neutrons, and electrons in
Concept introduction:
An atom is made up of three subatomic particles, which are neutrons, protons, and electrons. Neutron and protons are present in the nucleus of the atom, whereas electrons are revolving outside the nucleus in an atom. Isotopes are those atoms that have the same number of protons but a different number of neutrons.

Answer to Problem 26E

Explanation of Solution
The
The
The number of electrons and number of protons in a neutral atom is equal to its atomic number. Hence, the number of protons and number of electrons present in
