Mass of beta radiation?
A beta particle is an electron, with a mass of approximately 1/1840 of a proton
Are the rest mass of the positron and the electron exactly equal?
Yes; they simply have opposite charges.
What is the ratio of a proton to the mass of a neutron?
The mass of a proton and neutron are pretty close. So the ratio will be roughly 1 to 1 (or 1:1). The neutron is heavier and if memory serves it is exactly the mass of an electron heavier than a proton. Note it takes around 1820 electron to equal the mass of one proton.
Why doesn't the electron contribute to the mass?
They do, it's just such a small contribution that in practice it's usually negligible. It takes about 1800 electrons to equal the mass of one proton.
How does the mass of the nucleus compared to mass of an electron?
The mass of a nucleus varies according to the atomic number (ie according to what element it is). For hydrogen , the simplest nucleus, the combined mass of the one proton and the one neutron would be equal in mass to 3672 electrons.
Is The Mass Of An Electron Is Equal To The Mass Of A Neutrons?
No. The mass of a neutron is far, far, far greater than the mass of an electron. In fact, the mass of a neutron is approximately about 1840 times greater than the mass of an electron. The particle that has exactly the same mass as an electron is its antiparticle, the positron.
Do a neutron and an electron have approximately the same mass?
No, a neutron is about 1836 times the mass of an electron
Which two particles each have a mass approximately equal to one atomic mass unit?
The proton and the neutron each have a mass approximately equal to one atomic mass unit.
How does the mass of an electron compare to the mass of a proton and neutron?
The proton mass is about 2,000 times greater than the electron mass.
What Has approximately 1. 1840th the mass of a neutron?
an electron
What is the mass of a proton is approximately equal to the mass of?
The mass of 12 protons is approximately equal to 12 atomic mass units.
Mass of beta radiation?
A beta particle is an electron, with a mass of approximately 1/1840 of a proton
What is the mass and speed of beta radiation?
Mass= mass of electron Speed= Almost equal to that of light
What does the mass of an electron equal?
9.1*10^(-31)kg
Why isn't electron and positron mass equal?
Their masses are equal. It's their charges that are opposite.
Does a neutron have the same mass as an electron or a proton?
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
What is the atomic mass unit for neutron and electrons?
The atomic mass unit is approximately the mass of one neutron or proton. An electron has a mass of approximately 1/2000 of an amu.
