Proton Meaning: Definition, Examples, and Translations
💥
proton
[ˈproʊtɒn ]
Definition
particle physics
A proton is a subatomic particle found in the nucleus of an atom. It has a positive electric charge of +1 e and is one of the primary building blocks of matter, along with neutrons and electrons. Protons play a crucial role in determining the atomic number of an element, which defines its identity and position in the periodic table. The number of protons in the nucleus is referred to as the atomic number, and it has a direct influence on the chemical properties of the element.
Synonyms
nuclear particle, positively charged particle.
Examples of usage
- The atom's nucleus contains protons and neutrons.
- In hydrogen, there is just one proton.
- Protons are responsible for the positive charge of the nucleus.

Origin of 'proton'
Main points about word origin
- The word 'proton' comes from the Greek word 'protos', meaning 'first', reflecting its fundamental role in the structure of atoms.
- It was first coined in 1920 by British scientist Ernest Rutherford when he described the positively charged particle in atoms.
The term 'proton' comes from the Greek word 'protos,' meaning 'first.' This name reflects the proton's fundamental role in determining the properties of atoms. The concept of the proton was developed in the early 20th century, with important contributions made by physicists such as Ernest Rutherford and Henry Moseley. Rutherford, in particular, conducted experiments in 1911 that led to the understanding of the nucleus's structure and the discovery of the proton as a distinct particle. The classification of the proton as a fundamental particle became more refined as particle physics advanced, particularly in the 1930s and 1940s. As models of atomic structure evolved, protons were recognized as key components alongside neutrons, emphasizing their importance in both chemistry and physics.
