Question

When an electron is emitted, the mass number remains unchanged but atomic number increases by one unit. Nuclear reaction is:

• A. ${}_0^{1}n{⟶}_1^{1}H{+}_{-1}^{0}e$
• B. ${}_0^{1}n{⟶}_2^{1}H{+}_2^{0}e$
• C. ${}_0^{1}n{⟶}_3^{1}H{+}_1^{0}e$
• D. None of these

Answer 1

Answer: (A)

${}_0^{1}n{⟶}_1^{1}H{+}_{-1}^{0}e$

Nuclear reaction is as follows:

${}_0^{1}n{⟶}_1^{1}H{+}_{-1}^{0}e$

Here, a neutron emits a beta particle and converts into proton.
