Question

What is the particle "y' in the nuclear reaction Be+ He →C+Y
(C) proton
(D) neutron
(A) photon
(B) electron​

Answer 1

Answer

Explanation of the above's reaction

It is nuclear fission reaction between Beryllium and He⁺⁺( alpha particle)

In this reaction a thin foil of Beryllium is bombarded with He⁺⁺( alpha particle) which Results in production of a Carbon-12 atom and a free neutron.

Note :- Beryllium-9 is used for this purpose.

Nuclear Fission reaction :-

A nuclear reaction in which the larger atom decays into smaller and lighter nuclei .

Completed reaction :-

$( Be^9) + He^{++} \longrightarrow (C^{12}) + n^{0}$

So here Y = n⁰

Y = neutron

So Answer is option (D) neutron

Answer 2

Answer:

Explanation:Be+ He= C +n
