speed of an electron

What do you think about the speed of an electron, was it easy for scientists to find it? No! It was never easy to calculate because of the very small size of an electron. It has taken thousands of practicals, trials and errors, and tones of study to find an electron’s speed. Do you know? It is believed that the speed of a signal down a transmission line depends on the speed of an electron in a wire. But this is a false intuition, we might imagine that reducing the resistance of the interconnect will increase the speed of a signal. Let’s move forward and know about the speed of an electron

What Is The Speed Of An Electron? 

The speed of an electron is about 1 cm/sec. The maximum speed of electron varies with the medium such that the speed of electrons in wire is different from speed in magnetic fields and the same for all. Below, I will give you a formula to find all types of the speed regarding an electron. 

Let’s see the speed of an electron in different mediums and also see the speed of an electron formula

Calculate The Speed Of An Electron 

First of all, let’s learn about what is the speed of an electron around a nucleus and what is the formula to find it? 

So, the speed of an electron around a nucleus is around 2188 km/sec. And the general formula to find the speed of electron in the nth orbit is given by, 

Vn = 2.18 x 106 x Zn  

Here, Z is the atomic number of hydrogen atoms which is equal to 1. 

So, this is the speed of an electron in a hydrogen atom, let’s find the speed of electron in an electric field. 

 The speed or the velocity of an electron in an electric field changes under the influence of an electric field. Normally, we use formula to calculate this speed is as, 

vn = √(2eVa / m) 

Here, Vn is the classical or non-relativistic speed of electron 

          e – is the charge of an electron which is 1.602 × 10-19

          Va –  is the accelerating potential, and 

          m – is the mass of an electron which is 9.109 × 10-31 kg 

When it comes to an electric field. The voltage and current carrying conductor are always there. So, the speed of an electron from voltage is, 

V = 6 × 106 m/s 

And, the speed of electron in conductor is about 1mm per second. 

You should know about how to find the speed of an electron in an magnetic field also. 

In a magnetic field, the speed of an electron is 108 cm/s. You can use it as it is without calculating it from any formula. And lastly, you should know about the speed of electron in vacuum also which is 300 million meters per second. 

After knowing the speed of an electron in meters per second, let’s take a look over further information about an electron. 

About An Electron 

Now, you know about the speed of electrons. But you must know what an electron is. So, atoms consist of three basic components called electrons, protons, and neutrons. Based on the result of the 𝛼-scattering experiment, the physicist Ruthorford suggested that negatively charged electrons move in circular orbits around the positively charged region called the nucleus. 

The mass of electron is about 9.109 × 10-31kg and a charge of 1.602 ×10-19 C. When you want to find the speed of an electron then you can also use the electron speed calculator to escape from complex calculations. 

Electrons are extremely small compared to all of the other parts of the atom and the mass of an electron is almost 1000 times smaller than the mass of a proton. They play a mojo rle in all chemical bonds, there is one type of bonding called electrovalent bonding, where an electron from one atom is transferred to another atom. And this process continuously happens.

FAQ

What Is The Speed Of An Electron In An Atom?

Using these values along with the dielectric constant of free space to be 8.854 x 10 {+-} {+1}{+2} Farad per meter, it is possible to make an estimate of the speed of the electron in the circular orbit of the hydrogen atom to be about 2.188 x 10 {+6} meters per second or 2188 km/sec.

How Much Is The Speed Of The Electron?

An electron travels at a speed of about 1 cm/sec. This is about as fast as an ant scurries on the ground. With this simple analysis, we see that the speed of an electron in a wire is incredibly slow compared to the speed of light in air.

What Is The Max Speed Of An Electron?

about 300 million meters per second

By measuring the energy required to change the velocity of electrons as they jumped from one atomic orbital to another while Earth rotated over a 12-hour period, they determined that the maximum speed of an electron – in theory, the speed of light, about 300 million meters per second – is the same in all directions too.

How Do You Find The Velocity Of An Electron?

At speeds greater than 1/10th of the speed of light, we must use the relativistic formula to find an electron’s velocity in an electric field: v rel = c 1 − 1 ( 1 + e V a m 0 c 2 ) 2 .

Conclusion 

The speed of electrons and the theory behind it is impossible to cover in this article. It is because there is so much research and formulae for an electron. But, above we have given you some important formulae to calculate the speed of electrons easily. And you know now electrons are very important in the world of electronics. The very small particles can stream through wires and circuits, creating currents of electricity. So, from now on you will never forget about the speed of an electron
