Read each question carefully and provide your answers in the space provided. Ensure all nuclear equations are balanced correctly.
1. In a balanced nuclear equation, both the mass number and the number must be conserved.
2. Alpha decay results in the emission of a nucleus, which consists of two protons and two neutrons.
3. Beta decay involves the conversion of a neutron into a proton and an electron (beta particle), increasing the number by one.
4. Gamma radiation is a form of radiation and does not change the mass or atomic number of the nucleus.
5. Which of the following particles is represented by the symbol ⁰₋₁e?
Alpha particle
Beta particle
Neutron
Positron
