what type of radiation is emitted in the above problem?
1
a. radiation b. alpha c. beta d. gamma
e. neutron f. neutrino g. proton

Explanation:

In beta - decay, a neutron in the nucleus is converted into a proton and an electron (beta - particle). The atomic number increases by 1 while the mass number remains the same. Here, thorium (Th) with atomic number 90 decays to an element with atomic number 91, indicating a beta - decay.

Answer:

C. beta
