Nuclear Transmutations and Reactions

The video discusses nuclear transmutations, focusing on two types: alpha particle bombardment and neutron bombardment. Alpha particle bombardment involves smashing a helium nucleus into an atom, like nitrogen 14, resulting in a new element, such as oxygen 17. Neutron bombardment, exemplified by uranium 238, combines particles to form a new, often unstable element, like uranium 239, which may decay into other elements. The video emphasizes the conservation of mass and protons during these processes.

What is the primary focus of nuclear transmutations?

• Destroying existing particles

• Creating new particles from nothing

• Smashing particles together at high speeds

• Combining particles at low speeds

In alpha particle bombardment, what is an alpha particle composed of?

• Two protons and one neutron
