Interpretation : The number of neutrons in each isotope is to be calculated.
Concept Introduction : Atoms are divisible in nature. Subatomic particles are the fundamental particles formed by the breaking of atoms into smaller units.
The formula of neutrons is given as:
Answer to Problem 21SP
The number of neutrons in chromium-50, chromium-52, and chromium-53 are 26, 28, and 29 respectively.
Explanation of Solution
The three chromium isotopes are chromium-50, chromium-52, and chromium-53.
The
The mass number of chromium-50 is 50.
The mass number of chromium-52 is 52.
The mass number of chromium-53 is 53.
Neutrons are neutrally charged particles that are found inside the nucleus. The formula of neutrons is given as:
To calculate the number of neutrons in chromium-50, substitute the values in the above formula:
To calculate the number of neutrons in chromium-52, substitute the values in the above formula:
To calculate the number of neutrons in chromium-53, substitute the values in the above formula:
The number of neutrons in chromium-50, chromium-52 and chromium-53 are 26, 28, and 29 respectively.
