what does an electron weigh?
143616
Electrons have a rest mass of 9.109 x 10^-31 kg.  Which means they weigh 8.93 x 10^-30 N, which is about 2.01 x 10^-30 lbs.

electron\nThe electron is a lightweight fundamental subatomic particle that carries a negative electric charge. The electron is a spin-1/2 lepton, does not participate in strong interactions and has no substructure. Together with atomic nuclei, electrons make up atoms; they are responsible for chemical bonding. The flow of electricity in solid conductors is primarily due to the movement of electrons.\nhttp://en.wikipedia.org/wiki/Electron\n\nThe electron, denoted  is a fundamental particle with negative electric charge that is found arranged in quantum mechanical orbits about neutral atoms. The electron is a lepton, and therefore has lepton number 1. The antiparticle of the electron is called the positron. \n\nThe electron mass is  kg, and the electron charge , where  \nhttp://scienceworld.wolfram.com/physics/Electron.html

Yes the electricity is electron flow,which is the  number of electrons flowing in a cross section of a conductor for one oscilation .\nElectrons have an electrical mass which is equal to \n9.1 x10^-31kg.\nso if you take the number of electron per oscilation times the mass of the electron you have the total electrical mass flowing,\nYou take the total mass(assuming acceleration relative to the earth's center of mass)times 9.8 m/sec^2 would equal the weight of the electrical mass flowing.Hence a used battery would weight less.\nFor the simple reason that in the reaction gas has formed and evaporated and the excess electrons have dissipated and lost mass in the form of heat.\nThe weight difference can only be calculated. since the mass loss is very minute.The mass lost would be energy expanded by the battery divided by C^2.

Depends upon the experimental conditions.  Electrons are not hard little balls with a negative charge.  They are best thought of as areas of possibility for the location of a wave.  The angle of interaction, the relative velocity of the electron and proton and many other factors will determine the observed effect of their interaction.  Some believe that the expectations of the observer also plays a big role.  Neutrons have been “observed” to breakdown into an electron and a proton under some conditions.  The reverse seems possible.

It's a measure of energy where one electron volt is equal to 1.6 x 10^-19 Joules or 0.00000000000000000016 Joules.\n\nIt is the energy required to move an electron along a potential difference of 1 volt

one cannot measure electronegativity.it has been given on the Pauling scale given by Pauling .and charge can be determined by the valency of the element.

Use the periodic table to find the atomic mass of the element and subtract from this the atomic number.  \n\nThe atomic mass is equal to sum of proton and neutrons, and the atomic number is the number of protons an atom has.  Electrons have such a small mass that they don't really have any noticable effect on the atomic mass.\n\nEx: Oxygen (atomic mass - 16, atomic number - 8)\n\n16 - 8 = 8, therefore the number of protons is equal to 8

In solid state physics, a particle's effective mass is the mass it seems to carry in the semiclassical model of transport in a crystal. It can be shown that, under most conditions, electrons and holes in a crystal respond to electric and magnetic fields almost as if they were free particles in a vacuum, but with a different mass. This mass is usually stated in units of the ordinary mass of an electron m

if you want to know the number of electrons for a sample, you need to calculate the molarity of the substance and then multiply by the number of electrons that that element has. \n\nFor example:  you have 18 grams of water.  I picked that amount since the molecular weight of water is 18grams/mol.  (the mol weight of oxygen is 16 and 1 for hydrogen H2O =18grams of water is one mol of water)  A mol of sample is 6.02214199 × 10^23.  Yes thats a big number but its just like saying I have a dozen of something, a mol is a quantity of something.  I could have a mol of cars which would be 6.02x10^23 cars.  The reason we use such a big number is that there are so many atoms in even a tiny sample.  \n\nAnyways, 18 grams of water is one mol of water which is 6.02x10^23 molecules of water.  Now we need to figure out how many electrons are in one molecule of water and multiply it by the number of water molecules.  Oxygen has 8 protons and thus 8 electrons, hydrogen has 1 electron each, so a water molecule has 10 electrons.  So 6.02x10^23 times 10 more would equal 6.02x10^24 electrons in 18 grams of water.  (lots)

Nope, the magnetic information (not electronic!) doesn't weigh anything, it's all related to the orientation of the "magnetic moment" (up or down) of the atoms i.e. the way atoms are turning (to make it simple). they're not heavier if they turn in one sense than if they does in the other

No.. and yet... Here we go into quantum physics. One of the interesting things about your question is that it really depends on how you look at it. The observer actually affects what an electron is observed to be: basically- if you look for the electron to behave as a particle- it will. You will find that it has mass, and a velocity, etc. If you look for it to behave as a wave- you will find that as well. :) So, when it is a wave, it does have an innate frequency. Actually, it has one of several 'quantized' energy levels. If an electron gets excited (yes, physicists really use that term) it jumps up to a higher energy level. If it finds a way to release that energy (electromagnetic radiation, or light) it will return to is normal state. This explains many things in the real world, such as flourescent colors, photoluminesence, etc. Anyway- thats the quick version. For more depth, grab a modern physics book. :)

hey as me know they all are made of the elementary particles so than  the elementary particles are called quarks,theer are three type of quarks.they are the up quark,down quark & the middle quark.the value of these are that it is -1/3,1/3,1/3  so when it it made of three up quarks whose values are -1/3+-1/3+-1/3 that gives u the answer that is -1 there fore the charge of electron is -1ok

It means that electrons have both particle-like and wave-like behaviour (for example they demonstrate interference).\n\nwavelength = planck's constant/(mass x velocity)

electron is Negatively charged particle that revolves around the nucleus of an atom.IT shows dual character i.e; it has both wave character and particle character...one electronic charge is 1.609 * 10^-19......the wave length of an electron can be found using the formula lamda= h/mv..where h is the plank's constant 6.626*10^-34...m is mass of an electron 9.1*10^-31...v is its velocity...when supplied energy it gets excited and moves to high enegry orbital...then slowly radiate the energy and then move to their position...these radiations araethe colours seen when we heat substances...the color is due the wavelength of the radiations....the energy of an electron at infinity is 0...when it is near the nuclues...it does some work and energy is spent therefore near the nucleus he charge of an electron is -ve...thats all i can  remember...hope you slect mine...thanks....

The mass of protons and neutrons are nearly identical, the mass of an electron is about 1/1840th the mass of a proton, thus it is negligible, so you can't really tell its there.

According to quantum mechanics, electrons can be represented by wavefunctions, from which the electron density can be determined. Each electron has its own wavefunction, which is called an orbital. The exact momentum and position of an electron cannot be simultaneously determined. This is a limitation described by the Heisenberg uncertainty principle, which, in this instance, simply states that the more accurately we know a particle's position, the less accurately we can know its momentum, and vice versa.  So, exact postion of an electron impossible to determine.  Thus electron can be two places at ones.
