Atomic Structure

Modern Day Atom An atoms radius is 0.1nm Atomic mass unit (amu) Atoms are chemically neutral because the number of protons and electrons are equal Arrangement of electrons e.g., 2,8,1 Elements are arranged in order by their atomic number Proton - In nucleus, charge +1, mass of 1amu Neutron - In nucleus, charge 0, mass of 1amu Electrons - Energy Shells, charge -1, 1/1840 (almost zero)
