Interpretation : The atom that is composed of 16 protons, 16 electrons, and 16 neutrons is to be identified.
Concept Introduction : The number of protons and the number of electrons is equal to the
Answer to Problem 4STP
Correct answer:Option (C)
The atom that is composed of 16 protons, 16 electrons, and 16 neutrons is
Explanation of Solution
Reason for correct option:
The count of protons present in the nucleus of the atom gives the atomic number (Z).
The count of protons and neutrons present in the nucleus of the atom gives the mass number (A).
The general representation symbol of an element is given as
Where,
The given number of protons is 16, so the atomic number of the element is also 16.
The element with atomic number 16 is Sulphur. Its symbol is
The given number of neutrons is 16. The mass number is given as:
According the general representation of the element, the symbol is given as
So, option (C) is the correct answer.
Reasons for incorrect options:
Option (A): Since the number of protons and neutrons are 16, 16 respectively, the mass number would be 32, not 48.
Option (B): Since the number of protons is 16, the element will be Sulphur. In the option, the element is Germanium.
Option (D): The general
