Which atomic particle carries a positive charge?

The proton is the atomic particle that carries a positive charge. In the field of atomic physics, protons are one of the primary constituents of an atom, residing in the nucleus alongside neutrons. Their positive charge is integral in balancing the negative charge of electrons, which orbit the nucleus. This charge interaction is fundamental to the structure of atoms and contributes to the overall stability and chemical properties of elements.

Understanding the role of protons is essential, especially in the context of atomic behavior and interactions in radiation physics. Protons determine the atomic number of an element, which defines its identity in the periodic table. The positive charge of protons plays a crucial role in electromagnetic interactions, influencing how atoms bond and react chemically. This foundational knowledge is vital for those involved in dentistry and radiation safety, as it helps comprehend how atomic structure relates to various radiological practices.
