Bombardment of aluminum by alpha-particle leads to its artificial disintegration in two ways. (I) and (II) as shown. Products X, Y and Z respectively are, {:(._(13)^(27)Aloverset((ii))rarr ._(15)^(30)P + Y),((i) darr "" darr),(._(14)^(30)Si+ X"" ._(14)^(30)Si + Z):}

Answer»

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

Solution :`{:(""._(13)^(27)AL overset((ii) rarr 2 He^(4))rarr ._(15)^(30)P + underset((y)"neutron")(._(0)^(1)N)),((i) rarr ._(2)He^(4) darr"" darr),(""._(14)^(30)SI + underset((x)"proton")(._(1)^(1)p)"" ._(14)^(30)Si + underset((z)"positron")(._(1)^(0)e)):}`
