Curiously, this most common of atomic parts has only a fuzzy estimate of size.
Linus Pauling says "The radius of the electron has not been determined exactly, but it is known to be less than 1 X 10-13 cm".
So roughly the electron is 1/1000 the size of a proton. Maybe. But a cooler answer is-- physicists are annoyed by the question. A good case can be made for other sizes, even huge sizes....because the properties of the electron OTHER than it's size are the ONLY important ones. In fact the size of atomic pieces smaller than the nucleus usually does not matter at all....and may in fact have no meaning. After all, how do you propose to measure these guys?
The electron is known to be a point particle down to a limit of 10^-18m. It, as far as we know does not have a classical "size".
The ATOM decreases in size when it loses an electron and increases when electrons are added.
It is impossible to know exactly where an electron is. Thus, the size of an electron cloud can be given only in terms of probability. Even then, the size of the electron cloud depends on how many electrons an atom possesses.
When an atom gains an electron it increases in size, and when it loses an electron it decreases in size.
THIS is the electron cloud.
an atom is larger than an electron
electron is the smallest
If the electron were the size of a golf ball, the proton would be about the size of a basketball and the electron would be orbiting about 8000 meters away (assuming the Bohr model of the atom).
An electron is not the largest part of an atom. An electron is the smallest component of an atom. Relatively, if a neutron or proton were 1 unit in size, an electron would be 1/1840 units in size.
The size of a laser or electron beam is measured in milliradians. This is because they are subject to divergence.
Size can vary from a small scanning electron microscopes (SEM), about the size of a tower PC case that sits on a table top, to a million volt transmission electron microscopes (TEM) that is several stories tall.
An electron is about .03 meters small. An electron is about .03 meters small.
Can be seen with an electron microscopeits as big as a mouseViruses range in size from 12 nm to 450 nm .It is electron microscopic .
It shrinks loosing an electron.
When an electron is added to an atom, its size increases due to increase in repulsions between the electrons.
It grows smaller in size.
What factor determains the size of theelectron cloud
cost size and mass
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
The size of uranium atom depends on the number of electron around it
I need to know also
It is mostly related to the energy of the electron.
nope, an electron is nearly invisible when placed in a size comparison to a proton.
