![**Nuclear Equation Completion**
1. **Complete the nuclear equation for the alpha-decay of Th-232.**
\[
\text{Th-232} \rightarrow \text{-- ⟶} + \text{-- -- ⟶}
\]
- *Explanation*: In alpha decay, a thorium-232 nucleus emits an alpha particle, which consists of 2 protons and 2 neutrons. This results in a new element with a mass number reduced by 4 and an atomic number reduced by 2.
2. **Complete the nuclear equation for the beta-decay of Zn-69.**
\[
\text{Zn-69} \rightarrow \text{-- ⟶} + \text{-- ⟶} - \text{--}
\]
- *Explanation*: During beta decay, a neutron in zinc-69 is converted to a proton while emitting a beta particle (an electron). This increases the atomic number by 1, creating a new element, but the mass number remains unchanged.
3. **Complete the nuclear equation for electron capture in Ar-37.**
\[
\text{Ar-37} + \text{-- ⟶} \rightarrow \text{-- ⟶} - \text{--}
\]
- *Explanation*: In electron capture, an inner orbital electron is captured by the nucleus of an argon-37 atom, combining with a proton to form a neutron. This decreases the atomic number by 1, forming a new element, while the mass number remains the same.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F89b126cf-58b3-49ad-9704-387f30e63dfe%2F942b7ee3-19bf-454a-905f-b700b9522ef5%2F38ont8p_processed.jpeg&w=3840&q=75)
