The correct Answer is:
To solve the question regarding the nature of negatively charged emitted beta particles in the radioactive decay process, we can follow these steps:
### Step-by-Step Solution:
1. **Understanding Beta Decay**:
- Beta decay is a type of radioactive decay where a beta particle is emitted. There are two types of beta decay: beta-minus (β-) and beta-plus (β+). In this case, we are focusing on beta-minus decay.
2. **Identifying the Particle**:
- In beta-minus decay, a neutron in the nucleus of an atom is transformed into a proton. During this process, an electron (the beta particle) and an antineutrino are emitted.
3. **Source of the Beta Particle**:
- The emitted beta particle (electron) is not an electron that was already present in the atom's electron cloud. Instead, it is produced as a result of the decay of a neutron within the nucleus.
4. **Conclusion**:
- Therefore, the negatively charged emitted beta particles are the electrons produced as a result of the decay of neutrons inside the nucleus.
### Final Answer:
The negatively charged emitted beta particles are the electrons produced as a result of the decay of neutrons inside the nucleus.

During alpha-decay , a nucleus decays by emitting an alpha -particle ( a helium nucleus ._2He^4 ) according to the equation ._Z^AX to ._(Z-2)^(A-4)Y+._2^4He+Q In this process, the energy released Q is shared by the emitted alpha -particle and daughter nucleus in the form of kinetic energy . The energy Q is divided in a definite ratio among the alpha -particle and the daughter nucleus . A nucleus that decays spontaneously by emitting an electron or a positron is said to undergo beta -decay .This process also involves a release of definite energy . Initially, the beta -decay was represented as ._Z^AX to ._(Z+1)^AY + e^(-)"(electron)"+Q According to this reaction, the energy released during each decay must be divided in definite ratio by the emitted e' ( beta -particle) and the daughter nucleus. While , in alpha decay, it has been found that every emitted alpha -particle has the same sharply defined kinetic energy. It is not so in case of beta -decay . The energy of emitted electrons or positrons is found to vary between zero to a certain maximum value. Wolfgang Pauli first suggested the existence of neutrinoes in 1930. He suggested that during beta -decay, a third particle is also emitted. It shares energy with the emitted beta particles and thus accounts for the energy distribution. The beta particles (positron) are emitted with different kinetic energies because
