Mass of a proton, charge of a proton Mass of an alpha particle, charge of an alpha particle
Question
Mass of a proton, charge of a proton
Mass of an alpha particle, charge of an alpha particle
Solution
To find the mass of a proton, we can refer to the periodic table. The atomic mass of hydrogen is approximately 1.00784 atomic mass units (u). Since a proton is the nucleus of a hydrogen atom, its mass is also approximately 1.00784 u.
The charge of a proton is positive and equal to +1 elementary charge (e).
To find the mass of an alpha particle, we need to consider its composition. An alpha particle consists of two protons and two neutrons. The mass of a proton is approximately 1.00784 u, and the mass of a neutron is approximately 1.00867 u. Therefore, the total mass of an alpha particle is approximately 4.03134 u.
The charge of an alpha particle is positive and equal to +2 elementary charges (2e).
