What are the sizes of protons neutrons and electrons?

Answer 1

Proton and neutron has a size of 10-13 cm (approx. 1,5-2 fm).

The diameter of the electron may be cca. 10-17 m but this is only a calculated value and is not very sure.

Answer 2

there is no physical or mental answer unless you are ant man and you go and see the molecules yourself.

P.S. if you go, don't forget to take a tape measure

Answer 3

Because protons are not fundamental particles, they possess a measurable size; the root mean square charge radius of a proton is about 0.84–0.87 fm (or 0.84×10−15 to 0.87×10−15 m).

Answer 4

The wiki user is not correct how is it 10-17 meters

Answer 5

Well, isn't that a lovely question! Protons and neutrons are about the same size, roughly 1 femtometer in diameter. Electrons, on the other hand, are much smaller at about 0.00000000001 femtometers. Each of these tiny particles plays a special role in creating the beautiful world around us.

Answer 6

Oh, dude, protons and neutrons are both about 1 femtometer in size, which is like a quadrillionth of a meter. Electrons are way smaller, like around 0.0000000000001 femtometers. So, basically, protons and neutrons are like the big guys at the party, and electrons are just chilling in the corner, being all tiny and stuff.

Answer 7

Protons and neutrons are subatomic particles found in the nucleus of an atom. Protons have a mass of approximately 1 Atomic Mass unit (amu) and a radius of about 0.84 femtometers. Neutrons also have a mass of approximately 1 amu but are slightly larger in size with a radius of about 0.88 femtometers. Electrons, on the other hand, are much smaller with a mass of only about 1/1836 amu and are considered to be point particles with no definite size.

Answer 8

Protons and neutrons have similar sizes, with a radius of about 1 femtometer (10^-15 meters). Electrons are much smaller, with a radius estimated to be about 10,000 times smaller than protons and neutrons.

Answer 9

I have to know this for a math assignment and there's no answer lol

Answer 10

The sizes of protons are really tiny :) Also does any one like cheese
