1/1836 the mass of a proton
A beta particle is an electron, with a mass of approximately 1/1840 of a proton
Yes; they simply have opposite charges.
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.
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.
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.
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.
No, a neutron is about 1836 times the mass of an electron
The proton and the neutron each have a mass approximately equal to one atomic mass unit.
The proton mass is about 2,000 times greater than the electron mass.
an electron
The mass of 12 protons is approximately equal to 12 atomic mass units.

Their masses are equal. It's their charges that are opposite.
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
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.
