Question

Write down the expression for nuclear radius in terms of mass number.

Answer 1

to find the expression for nuclear radius in term of mass number we have to miss know about

Answer 2

Answer:

Radius of the nucleus is proportional to the cube root of its mass number

Step-by-step explanation:

• Hint: Atomic nucleus is a small and dense region consisting of protons and neutrons at the center of an atom discovered by Ernest Rutherford in 1911. The size of the radius of the nucleus is 1-10 FM or femtometre.
• The maximum mass of an atom is concentrated in the nucleus with negligible contribution from electrons. Nuclear force binds protons and neutrons to form a nucleus. Nuclear radius (R) is one of the basic quantities. For a stable nucleus, the nuclear radius is approximately proportional to the cube root of the mass number (A) of the nucleus and the nucleons arranged in more spherical configurations.
• Mathematically, represented as$R = R_{0} 0A^{1/3}$, where R is the radius and A is the atomic mass number (the number of protons plus the number of neutrons), and R0is 1.25×10−15m. The stable nucleus has approximately a constant density.
• The correct answer to this question is option ‘c’ that the radius of the nucleus is proportional to the cube root of its mass number.
