What is the weight of an electrion on the surface of the earth?

Question

and if you could briefly, how did you come to that conclusion?

Answer 1

Effectively zero; electrons have no mass for all intents and purposes. In fact, they behave more like waves than particles.

Answer 2

Bingo Paula! An electron has an absolute mass of 9.11 x10^-28 g (or 10^-31kg), and the proton and neutron have absolute masses of ~ 1.67 x 10^-24 g . It is in relative (amu) mass that the electron has almost no mass.

Answer 3

And let's not forget - since this is the Physics forum - that we should apply the Physics definition of weight = mass x acceleration due to gravity = (9.11 * 10^-31)(9.81) = 8.94 * 10^-30 N.

Answer 4

well, there are 1832 electron masses in an amu, and A [6.02 x 10^23] amu's in a gram.

So take a gram, divide it by both those numbers together.

1 gram divided by (1832 x A)=
1 gram divided by (1102864000000000000000000000)

That's it.

Answer 5

if i remember correctly, when i took chem in high school, the textbook said that the mass of an electron is so small, its considered insignificant. its mass is 9.11×10-31 kg.

Answer 6

w=mg
w=(9.11x10^-31 kg)(9.8 m/s/s)
