Which of the following processes involves the emission of a positron? (2019)
Step 1: Understand what a positron is. A positron is a particle that is similar to an electron but has a positive charge.
Step 2: Learn about beta decay. Beta decay is a type of radioactive decay where an unstable atomic nucleus transforms into a more stable one.
Step 3: Identify the types of beta decay. There are two types: beta minus decay (which emits an electron) and beta plus decay (which emits a positron).
Step 4: Focus on beta plus decay. This is the process that specifically involves the emission of a positron.
Step 5: Conclude that the process involving the emission of a positron is beta plus decay, which is a part of beta decay.
