Calculate the uncertainty in its velocity if the uncertainty in its position were of the order of `10^(-11)m (h = 6.6 xx 10^(-34) kg m^(2) sec^(-1))`
The electron has a magnetic dipole moment by virtue of its spin. The approximate value of the dipole moment is the Bohr magneton μ 0 which is equal to eh/4πmc = 9.27 × 10-21 erg/oersted, where e is the electron charge measured in electrostatic units, m is the mass of the electron, and c is the velocity of light. The mass of electrons is ignored in calculating an approximate atomic mass, because an electron's mass is only about 1/1836.1 of the mass of a proton or neutron.
The electron rest mass (symbol: m e) is the mass of a stationary electron, also known as the invariant mass of the electron. It is one of the fundamental constants of physics.It has a value of about 9.109 × 10 −31 kilograms or about 5.486 × 10 −4 daltons, equivalent to an energy of about 8.187 × 10 −14 joules or about 0.5110 MeV.
The mass of a proton is 2000 times the mass of an electron. Mass of electron: 9.10938 * 10-31 kg Mass of proton: 1.67262 * 10-27 kg Mass of neutron: 1.67493 * 10-27 kg Note that protons and. Electron Charge and Mass Quantity Symbol Value Units Mass me 9.109 x 10-31 kg Charge e 1.602 x 10-19 C I. The Charge to Mass Ratio (e/m) for the Electron Introduction In 1897 J. J. Thompson discovered the first "elementary particle", the electron, by measuring the ratio of its charge to mass in a manner similar to the experiment that we will. 1 What is the approximate mass of a proton?

The sodium atom becomes (1) a positive ion (2) a negative ion (3) an atom in an excited stale The approximate mass of an electron is `10^(-27)g`. Calculate the uncertainty in its velocity if the uncertainty in its position were of the order of `10^(-11)m (h = 6.6 xx 10^(-34) kg m^(2) sec^(-1))`
