Question

Match the following items. 1. high-intensity bundle of energy being emitted from some decaying nuclei gamma ray 2. particle radiating from the nucleus of some atoms beta particle 3. negative particle identical to an electron but radiating from a decaying nucleus alpha particle

Answer 1

Step-by-step explanation:

1. high-intensity bundle of energy being emitted from some decaying nuclei → gamma ray.

Gamma ray: Penetrating electromagnetic radiation with high intensity of energy which arises from the decaying of an atomic nuclei.

`_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta`

2. particle radiating from the nucleus of some atoms →alpha particle

Alpha decay: In this process, alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units.

`_Z^A\textrm{X}\rightarrow _(Z-2)^(A-4)+_2^4\alpha`

3. negative particle identical to an electron but radiating from a decaying nucleus → beta particle

Beta-decay: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

Answer 2

1. High-intensity bundle of energy being emitted from some decaying nuclei = gamma ray
2. Particle radiating from the nucleus of some atoms = alpha particle
3. Negative particle identical to an electron but radiating from a decaying nucleus = beta particle
