Question

The radius of Ge nucleus is measured to be twice the radius of 9 Bc 4.How many nucleons are there in Ge nucleus.​

Answer 1

Answer:

Hey there!

For your question, please note one basic formula from the 'Nuclei' chapter.

R= R₀ ∛A where R= radius of given atom, R₀= constant ( 1.2 × 10⁻¹⁵ m or 1.2 fermi- meter) and A= mass number or number of nucleons

Now we have the radii ratio of Ge and Be provided as 2/ 1. R₀ is a constant.

Therefore, R ∝ ∛A

⇒ R₁ / R₂ = ∛ (A₁ / A₂)

⇒ 2= ∛( A₁ / 9)

⇒ 8= (A₁ / 9)

⇒ A₁= 72

Number of nucleons in Ge = 72.

Hope this helps!
