What is the atomic mass of an electron?
an electron is about 1/1836 amu.
What is the ratio of the mass proton to the mass of an ELECTRON?
Dunno, but the ratio of the mass of a proton to the mass of what prople think of as being an electron is approx 1980. I'd check that if I were you though. Probably OK to +- 5%.
How does the mass of a nucleus compare to a electron?
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.
What is the mass of an electron approximately equal to?
1/1836 the mass of a proton
What is Electron Relative mass?
it is usually the mass without the x10^-31
Is difference of mass number is calculated by electron microscope?
no, the mass spectrometer.
What is the mass of 1 electron?
1/1836 of an electron is the mass of an electron. It is so small they aren't even calculated in the Atomic Mass of an element
Why is mass number calculated with only the protons and neutrons and not electrons?
Because the mass of electron is negligible when compared to the mass of protons or neutrons.
When is the mass of an electron regarded as zero?
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
What is a protons mass calculated by?
The mass of a proton is calculated to be approximately 1.6726 x 10^-27 kilograms. This value is determined through experiments and measurements of the particle's mass and properties.
The rest mass energy of an electron positron pair is?
The rest mass energy of an electron-positron pair is equivalent to the combined rest mass of the two particles, according to Einstein's equation E=mc^2. The rest mass energy can be calculated by adding the rest masses of an electron and a positron, which are equivalent to their respective rest masses multiplied by the speed of light squared.
Is an electron a standing wave?
No -- an electron is a point particle with mass, charge, and spin. The probability that you will find an electron at a specific point can, however, often be calculated by wave functions. Any moving mass can be considered either a particle or a wave. Its properties can be defined via the deBorlie wave equation.
An atom of tritium an isotope of hydrogen has 1 proton 2 neutrons and 1 electron What is its mass in amu?
The mass of tritium (T) can be calculated by adding the masses of its constituents. The mass of a proton is approximately 1.0073 amu, the mass of a neutron is approximately 1.0087 amu, and the mass of an electron is negligible. So, the mass of tritium would be approximately 3.016 amu.
What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
What is the characteristic wavelength of the electron when an electron is accelerated through a particular potential field if it attains a speed of 9.38x10 to the power of 6 ms?
The characteristic wavelength of an electron accelerated through a potential field can be calculated using the de Broglie wavelength formula: λ = h / p, where h is the Planck constant and p is the momentum of the electron. Given the speed of the electron, momentum can be calculated as p = m*v, where m is the mass of the electron. Once the momentum is determined, the wavelength can be calculated.
