Give the symbol for (b) a beta particle.

Verified step by step guidance

1. Understand that a beta particle is a high-energy, high-speed electron or positron emitted in the radioactive decay of an atomic nucleus.
2. Recognize that there are two types of beta particles: beta-minus (β-) and beta-plus (β+).
3. Identify that a beta-minus particle is an electron, which is represented by the symbol \( \beta^- \) or \( e^- \).
4. Identify that a beta-plus particle is a positron, which is represented by the symbol \( \beta^+ \) or \( e^+ \).
5. For the purpose of this problem, the symbol for a beta particle is typically \( \beta \), but specify \( \beta^- \) for an electron and \( \beta^+ \) for a positron if needed.

Key Concepts

Beta Particle

A beta particle is a high-energy, high-speed electron or positron emitted during the radioactive decay of an atomic nucleus. It is a type of radiation that occurs when a neutron in the nucleus transforms into a proton, emitting an electron (beta-minus) or when a proton transforms into a neutron, emitting a positron (beta-plus).

Symbol for Beta Particle

The symbol for a beta particle is typically represented as 'β' for beta-minus (electron) and 'β+' for beta-plus (positron). These symbols are used in nuclear equations to denote the emission of beta radiation during decay processes.

Radioactive Decay

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This can occur in various forms, including alpha, beta, and gamma decay, and is a fundamental concept in nuclear chemistry and physics, influencing the stability and transformation of elements.
