What is the relative mass of an electron?

The relative mass of an electron is approximately 1 ÷ 1836 , or 0.00054858, relative to the mass of a proton or neutron.
The mass of an **electron **is significantly smaller compared to the mass of a proton or neutron. The exact value of the relative mass of an electron is derived from the mass-to-charge ratio in the context of the atomic mass unit (amu) scale.
The relative mass of an electron is often expressed in comparison to the mass of a proton or neutron. In the context of the **atomic mass **unit (amu) scale, the mass of a proton or neutron is considered to be approximately 1 atomic mass unit, while the mass of an electron is much smaller.

The relative mass of an electron is incredibly small compared to other subatomic particles such as protons and neutrons. The mass of an electron ( me ) is 9.11×10-31 kg. This value is about 1/1836 of the mass of a proton, meaning an electron's mass is approximately 0.0005 atomic mass units (amu), where 1 amu is defined as one twelfth of the mass of a carbon-12 atom.

The relative mass of an electron is approximately 1/1836 of a proton or neutron, making it about 0.00055 amu. Electrons are significantly lighter than protons and neutrons, contributing minimally to an atom's overall mass. While the mass of an electron is very small, its charge is important in determining chemical properties.
