## Chemistry: A Molecular Approach (3rd Edition)

The basic properties of each are as follows: Proton : Mass (kg) = $1.67262 \times 10^{-27}$ kg Mass (amu) = $1.00727$ amu Charge (relative) = $+1$ Charge (C) = $1.60218 \times 10^{-19}$ C Electron: Mass (kg) = $0.00091 \times 10^{-27}$ kg Mass (amu) = $0.00055$ amu Charge (relative) = $-1$ Charge (C) = $-1.60218 \times 10^{-19}$ C Neutron: Mass (kg) = $1.67493 \times 10^{-27}$ kg Mass (amu) = $1.00866$ amu Charge (relative) = $0$ Charge (C) = $0$ C
