\({ }_{6} \mathrm{C}^{12}\) absorbs an energetic neutron and emits a \(\beta\) Particle. The resulting nucleus is (A) \({ }_{7} \mathrm{~N}^{13}\) (B) \({ }_{7} \mathrm{~N}^{14}\) (C) \({ }_{6} \mathrm{C}^{13}\) (D) \({ }_{6} \mathrm{C}^{12}\)

Short Answer

Expert verified
The resulting nucleus after the absorption of a neutron and emission of a beta particle is \({ }_{7} \mathrm{N}^{13}\). The correct answer is option (A).

Step by step solution

01

Identify the initial nucleus

The initial nucleus given in the problem is Carbon-12, which can be written as \({ }_{6} \mathrm{C}^{12}\). This means that it has 6 protons and 6 neutrons (12-6=6).
02

Absorption of a neutron

When the Carbon-12 nucleus absorbs a neutron, its neutron count increases by 1. So, the new nucleus will have 6 protons and 7 neutrons, making it Carbon-13 (\({ }_{6} \mathrm{C}^{13}\)).
03

Emission of a beta particle

A beta particle is an electron that is emitted during a beta decay process, in which a neutron changes into a proton. In this reaction, one of the 7 neutrons will change into a proton, so the resulting nucleus will have 7 protons and 6 neutrons (7+6=13).
04

Identify the final nucleus

The final nucleus will have 7 protons and 6 neutrons, which corresponds to Nitrogen-13. Hence, the resulting nucleus after the absorption of a neutron and emission of a beta particle is \({ }_{7} \mathrm{N}^{13}\). So, the correct answer is option (A) \({ }_{7} \mathrm{~N}^{13}\).
