Bombardment of aluminium of alpha- particle leads to its artificial disintegration in two ways (i) and (ii) as shown below. Product X,Y, and Z, respectively, are ._(14)Si^(30)+Xoverset((i))larr._(13)Al^(27)overset((ii))rarr._(15)P^(30)+Y rarr ._(14)Si^(30)+Z

Answer»

Proton, neutron, positron
Neutron, positron, proton
Proton, positron, neutron
Positron, proton, neutron

Solution :`underset(._(2)He^(4)darr(i))(._(13)Al^(27)overset(._(2)He^(4)))rarr underset(darr(II))(._(15)P^(30)+._(0)N^(1)(y)`
`._(14)SI^(30)+._(1)p(x)^(1)``._(14)Si^(30)+._(1)e^(+0)(Z)`
`:. x:` Protons, `y:` neutron, `z:` positron
