Write a balanced equation for each of the following nuclear reactions: (a) the production of \(^{17} \mathrm{O}\) from \(^{14} \mathrm{N}\) by \(\alpha\) particle bombardment (b) the production of \(^{14} \mathrm{C}\) from \(^{14} \mathrm{N}\) by neutron bombardment (c) the production of \(^{233}\) Th from \(^{232}\) Th by neutron bombardment (d) the production of \(^{239} \mathrm{U}\) from \(^{238} \mathrm{U}\) by \(_{1}^{2} \mathrm{H}\) bombardment

Understanding how to balance nuclear equations is essential when studying nuclear chemistry. Nuclear reactions differ from chemical reactions; instead of dealing with electron transfers, they involve changes within the atomic nuclei. It can be puzzling at first, because the focus is on the conservation of both atomic and mass numbers.

Let's break it down: The atomic number, which represents the number of protons, and the mass number, which is the sum of protons and neutrons, must remain the same before and after the reaction. When balancing a nuclear equation, like the production of oxygen-17 from nitrogen-14 through alpha particle bombardment, an alpha particle must collide with a nitrogen nucleus, producing oxygen-17 and a leftover proton. It's much like solving a puzzle, ensuring that the pieces, or in this case the atomic and mass numbers, fit perfectly on both sides.

Particle bombardment is an intriguing process where particles like alpha particles, neutrons, or deuterons are directed at a nucleus, instigating a nuclear reaction. The bombardment leads to a transformation within the target nucleus, often resulting in the formation of a different element or isotope.

For example, nitrogen-14 can absorb an alpha particle to form oxygen-17, releasing a proton in the process. This type of interaction is key in nuclear physics and has practical applications in fields such as medicine, where particle bombardment is used in cancer treatments. In learning environments, this process demonstrates the dynamic nature of atomic nuclei and the power of small particles to effect transformative change.

Neutron capture is a type of nuclear reaction in which a neutron, which is neutrally charged, is added to a nucleus. Because neutrons are neutral, they can penetrate the nucleus without being repelled by the positively charged protons. The result of neutron capture is typically an isotope with a mass number one unit higher, while the atomic number remains unchanged.

For instance, when thorium-232 captures a neutron, it becomes thorium-233. This is an excellent example of how nuclear reactors work, by continuously capturing neutrons to transform elements. Neutron capture is a fundamental concept in nuclear physics, and understanding this process helps explain how new isotopes are formed naturally and artificially.

An alpha particle is a type of nuclear particle that can be involved in nuclear reactions. This particle is essentially a helium nucleus, consisting of two protons and two neutrons. The signature of alpha decay is the release of these particles from unstable nuclei in an attempt to reach a more stable state.

Alpha particles have a +2 charge due to their two protons, and they are relatively heavy and slow-moving compared to other forms of radiation like beta or gamma rays. Although they can't penetrate human skin, they pose a significant danger if ingested or inhaled. The role of alpha particles in nuclear reactions, such as the bombardment of nitrogen-14 to produce oxygen-17, showcases their ability to transform one element into another, illustrating the powerful forces at play within the heart of atoms.
