Question

Find the reaction which decreases the neutron-to-proton ratio in a nucleus.

• A. ${}_{92}^{234}U{\to }_{90}^{230}Th{+}_2^{4}He$
• B. ${}_6^{14}C{\to }_7^{14}N{+}_{-1}^{0}e$
• C. $A{g}^{+}+B{r}^{-}\to AgBr$
• D. $2HgO\to 2Hg+O_2$
• E. ${}_{15}^{30}P{\to }_{14}^{30}Si{+}_1^{0}e$

Answer 1

Answer: (B)

${}_6^{14}C{\to }_7^{14}N{+}_{-1}^{0}e$

The reaction ${}_6^{14}C{\to }_7^{14}N{+}_{-1}^{0}e$ decreases the neutron-to-proton ratio in a nucleus. In this reaction, a neutron is converted into a proton and electron.
