Question

A nucleus of 4 Bc 9 absorbs an alpha particle and emits a neutron. The resulting nucleus will be (A)  5 C 13 (B)  6 C 12 (C)  6 C 13 (D)  4 BE 8

When one α -particle is absorbed and onc neutron is emitted then the balance equation shows that resulting nucleus will be carbon. The balance equation is 4 Be9+ underset text(α -particle)2He4→ underset text(neutron)0n1+6C12 (α -particle) (ncutron) From this equation, we find that atomic wcight is 12 and atomic mass number is 6 . Since both these values are meant for carbon (C), thercfore resulting nucleus will be, 6 C 12.
