Subatomic particle with positive electric charge. The name is of Greek origin by 960; 961; 969; 964; 959; 957; ( proton "the first, initial" ) and the physicist Ernest Rutherford used it in 1918 when he found that nitrogen decayed into hydrogen nuclei, so he assumed that H (atomic number 1) was a fundamental particle for other elements. However, it was already known that atoms were made up of electrically charged particles, and then 'proton' was associated with positive ones.
