Question

How do alpha particles interact with matter?

Answer 1

Answer:

Explanation:

Electrostatic attraction between the two positively charged of an alpha particle and the single negatively charged of an orbital electrons cause ionizations and excitation events. As the positively charged alpha particle moves through matter, it attracts many orbital electrons leaving a wake of ion pairs. When the speed is slowed enough, the alpha particle will capture electrons.

Answer 2

it's the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they interact. Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.
