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.
What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
Mass number of an electron?
The mass number of an electron is 5.485 799 095 x 10-4 amu.
What is the number of atomic mass in an atom?
Relative mass number of an electron is 0
What particle has the lowest mass number?
The particle with the lowest mass number is the electron, which has a mass number of 0. This is because electrons are considered to be fundamental particles and do not consist of smaller subatomic particles like protons and neutrons.
What is the mass number of an electron?
An electron has a mass of 9.109 X 10-31 kg, approximately 1⁄1840 the mass of a proton. However, the term mass number doesn't apply to electrons, it applies to atomic nuclei. The mass number of a nuclear isotope is the total number of protons and neutrons, together known as nucleons, of the isotope, and is denoted by (A).
What is the number of neutrons mass atomic protons electrons in tritium?
1 proton 1 electron 2 neutrons mass = 3 amu
Is difference of mass number is calculated by electron microscope?
no, the mass spectrometer.
Why does the mass number exclude the mass of an electron?
Because the electron is so light that modern technology is not advanced enough to measure it.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
Is the mass number equal to the number of protons and electrons?
No, it isn't. The mass of an electron is significantly smaller than that of a proton.The mass of 1,800 electrons is about the same as the mass of one single proton.The antiparticle of the electron, the positron, has the same mass as the electron.the mass of the electron is not the same to the mass of the proton
What happen to atomic number and mass number of nucleus when it emits electron?
When a nucleus emits an electron, the atomic number increases by 1 since the nucleus gains a proton. However, the mass number remains the same because an electron is much lighter than a proton or neutron.
