Question

Complete the following equations:
a) 30^P +......->300^Si
b)10^B+n->....+α
c)20^Ne+136^Ba->150^Dy+....
d).....+2^H->22^Na+α

Answer 1

Task #81483

Solution.

These reactions are devoted to alpha and beta radiation. An alpha particle is a helium atom with an atomic mass of 4 and charge 2. A beta particle is an electron with an atomic mass approximately equal to unity and a charge of -1. In addition, you most likely have an error in a). Since silicon isotopes do not have an atomic mass of 300. It can only be in the vicinity of 30.

a) $^{30}_{15}\mathrm{P} + ^{0}_{-1}\mathrm{e} - > ^{30}_{14}\mathrm{Si}$

b) $^{10}_{5}\mathrm{B} + ^{1}_{0}\mathrm{n} - > ^{7}_{3}\mathrm{Li} + ^{4}_{2}\mathrm{He}$

c) $^{20}_{10}\mathrm{Ne} + ^{136}_{56}\mathrm{Ba} - > ^{150}_{66}\mathrm{Dy} + 6\ ^{1}_{0}\mathrm{n}$

d) $^{24}_{12}\mathrm{Mg} + ^{2}_{1}\mathrm{H} - > ^{22}_{11}\mathrm{Na} + ^{4}_{2}\mathrm{He}$

Answer:

a) $^{30}_{15}\mathrm{P} + ^{0}_{-1}\mathrm{e} - > ^{30}_{14}\mathrm{Si}$

b) $^{10}_{5}\mathrm{B} + ^{1}_{0}\mathrm{n} - > ^{7}_{3}\mathrm{Li} + ^{4}_{2}\mathrm{He}$

c) $^{20}_{10}\mathrm{Ne} + ^{136}_{56}\mathrm{Ba} - > ^{150}_{66}\mathrm{Dy} + 6\ ^{1}_{0}\mathrm{n}$

d) $^{24}_{12}\mathrm{Mg} + ^{2}_{1}\mathrm{H} - > ^{22}_{11}\mathrm{Na} + ^{4}_{2}\mathrm{He}$
