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%.
What is Electron Relative mass?
it is usually the mass without the x10^-31
What is the mass of an electron approximately equal to?
1/1836 the mass of a proton
Can you explain why the estimation of the diameter of an atom is greater or less than the known value?
Here's a guess... Without getting overly complicated.... The diameter of the atom isn't just the diameter of the atom's nucleus... it is the diameter of the whole atom including the electron cloud surrounding the nucleus. As the name implies, an electron cloud represents all the possible locations that the electron could be. This cloud has thickness and therefore the atom could be smaller if the electron is in a portion of the cloud closer to the nucleus or larger is the electron is in a portion of the cloud farther from the nucleus. The "known value" is probably just the average of the two. Therefore, an atom's diameter has a range rather than a fixed value.
