ocr: 1. Atomic Structure Atom Proton Proton Neutron Electron Properties: The proton has a mass of 1,673x 10:27kg, which is 1836 times as big as an electron. The mass of the proton is almost the same: as that of a neutron. Ith has a positive electric charge of1.6x 10-19 coulombs, equal in size but opposite in charge to that of an electron. The charge is usually written as +e, implying that itis equivalent to the charge of an electron but positive. Page 1d 4
