Beta Decay
Definition:
Beta decay is a process that occurs in some types of unstable atoms (called isotopes) where the nucleus (the center part of the atom) changes and releases a particle called a beta particle. This process helps the atom become more stable.
Usage Instructions:
- "Beta decay" is a noun, so it is used to name this specific process. - It is often used in scientific contexts, especially in physics and chemistry.
Example:
- "Carbon-14 undergoes beta decay to transform into nitrogen-14."
Advanced Usage:
In more advanced discussions, you might encounter phrases like "beta decay is a type of radioactive decay," or "the energy released during beta decay can be measured in electron volts."
Word Variants:
- Beta particle: The particle emitted during beta decay, which can be either an electron (beta-minus decay) or a positron (beta-plus decay). - Decay: This refers to the process of breaking down or changing over time, often used in different scientific contexts.
Different Meanings:
In general, "decay" can refer to the process of deterioration or decline in various contexts, such as "tooth decay" (the deterioration of teeth) or "organic decay" (the process of rotting).
Synonyms:
- Radioactive decay - Nuclear decay
Idioms and Phrasal Verbs:
While there are no specific idioms or phrasal verbs directly related to "beta decay," you might hear phrases like "decay over time," which refers to a gradual decline in quality or condition in a more general sense.
To sum it up, "beta decay" is a scientific term that describes a specific way that certain unstable atoms change to become more stable by emitting beta particles.
