Detailed explanation-1: -A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
Detailed explanation-2: -The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons). A proton is made of two Up quarks, with 2/3 positive charge each and one Down Quark with a negative 1/3 charge (2/3 + 2/3 +-1/3 = 1).
Detailed explanation-3: -A proton being positively charged is just a convention. It is not the usual “positive” you think about. We found out that there can be three kinds of charges-two of which attract to each other and the third is “neutral” to the. So, we decided to name them positive, negative and neutral.
Detailed explanation-4: -positron, also called positive electron, positively charged subatomic particle having the same mass and magnitude of charge as the electron and constituting the antiparticle of a negative electron.
