Question

1. emission increases the stability of the nucleus
2. not deflected by any magnetic or electrical fields
3. write the nuclear decay equation for thorium - 230 undergoing alpha decay

$_{90}^{230}th\
ightarrow_{88}^{226}ra + _{2}^{4}he$

1. write the nuclear decay equation for $_{3}^{8}li$ emitting a beta particle

$_{3}^{8}li\
ightarrow_{4}^{7}be+_{ - 1}^{0}e$

1. thorium - 234 can undergo beta particle production. what is the other product?

Explanation:

Step1: Recall beta - decay rule

In beta - decay, a neutron in the nucleus changes to a proton and an electron (beta particle). The atomic number increases by 1 and the mass number remains the same.

Step2: Write the decay equation for Th - 234

$^{234}_{90}Th
ightarrow^{234}_{91}Pa + _{- 1}^0e$

Answer:

$^{234}_{91}Pa$
