WebbThere are two types of particle in the nucleus of an atom: the proton and the neutron. The proton has a positive charge and a large mass (1800 times more than an electron – see table 1). The number of protons in a nucleus is the same for all the atoms of a particular element. It corresponds to the atomic number of that element. http://resources.schoolscience.co.uk/STFC/16plus/partich1pg2.html
