The subatomic particles with a positive charge are called protons. Protons are found in the nucleus of an atom along with neutrons. They contribute to the atomic number of an element, which is the number of protons in the nucleus. For example, if an atom has 6 protons, it is a carbon atom because the atomic number of carbon is 6.
In summary, protons are positively charged subatomic particles found in the nucleus of an atom, and they determine the element's identity by contributing to the atomic number.
