Is the position and velocity of an electron in an atom be determined with great certainty?

Not exactly. Electrons orbit the nucleus in an atom.
An atom is a fundamental piece of matter. (Matter is anything that can be touched physically.) Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms.
An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud. The electrons carry a negative charge and the protons carry a positive charge. In a normal (neutral) atom the number of protons and the number of electrons are equal. Often, but not always, the number of neutrons is the same, too.

∙ 14y agoThe Heisenberg uncertainty principle states that it is impossible to know both the location and direction of an electron. You can know the location, but then the direction of the electron will change. If you find the direction, the location will change.

∙ 10y agothe problem with that is that electrons are very tiny and move very quickly, that it would be nearly impossible to track the exact position of an electron, ones that stay still are protons and neutrons so i think it would be more reasonable to track that instead.

∙ 14y agoyes we can but it take some research and time....

∙ 14y agoA fundamental principle of modern physics is that the exact position of an electron cannot be determined.

∙ 11y agoNo, it is not possible to determine the exact location of an electron in an atom. Instead you can only calculate the electron's probable location within the atom.
Wiki User
∙ 11y agoIt's quite impossible at the moment. Thus, the best one can do is to assume that the electron is located in an orbital, a volume which it is 99% likely to be in.

∙ 11y agono, atomic theory now allows you to calculate the position to a 90/95% probability. So EXACT is no.

What is the velocity of an electron with a mass of 9.11 x 10-31 kg at a position with an uncertainty of 5x10-10 m?
Do you mean the free mean path velocity, or the absolute velocity over a specific distance (molecular diffusion)?
Where the location of electron?
There is no exact location of the electron. The electron is outside the nucleus orbiting the center of the atom. You can't see it because it rotates so fast and is so small. So we can't indicate the exact location of the electron.
Who said that the location and velocity of an electron couldn't be known?
Heisenberg
Why does the uncertainty principle make it impossible to predict a trajectory for the electron?
A wave does not have a discrete position, it has an area, a line defining its location maybe, but never a point. You can say that a wave has a focus point (a circular wave has a center) but such a point is not where any part of the wave is - where it was maybe - but not where it now is.The fact that an electron is a wave (we may think of it as one in certain circumstances) ensures that it does not have a definite position.
What is the wavelength of an electron moving with a velocity of 2.5 x 108 cm s1?
Wavelength = Plancks constant / (Mass x Velocity)
Why can we not accurately predict where in the electron cloud electrons can be found?
We cannot accurately predict where in the electron cloud electrons can be found because of the Heisenberg uncertainty principle. This principle states that it is impossible to simultaneously know the exact position and momentum of an electron. As a result, we can only describe the probability distribution or the likelihood of finding an electron in a particular region of the electron cloud.
Under what circumstance can you know the velocity of an electron with great accuracy?
Only when the position is zero.
Is drift velocity the velocity of an electron or its displacement?
It is type of velocity of electron.
How measuring the position of an electron changes its velocity?
The only logical answer is to get drunk and set fire to things.
Why is it impossible to know precisely the velocity and position of an electron at the same time.?
This is because of the Heisenberg uncertainty principle. It is a part of quantum mechanics. It has to do with an electron having properties of both a particle and and wave. If you only imagine an electron to be a particle, this can be somewhat explained by the process of measuring the position or velocity of the electron. If the data is measured with light, then when a photon hits the electron, it changes the electrons speed and position. We may be able to find one, but in the process, the other will be changed.
What information can be learned from a position-time graph and from a speed-time graph?
A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.
What is velocity determined by?
I believe Velocity is determined by speed and time.
What is the velocity of an electron with a mass of 9.11 x 10-31 kg at a position with an uncertainty of 5x10-10 m?
Do you mean the free mean path velocity, or the absolute velocity over a specific distance (molecular diffusion)?
How do you find actual velocity?
To find the actual velocity of an object, you need to know both the magnitude and direction of its velocity. This can be determined using various methods depending on the situation. For example, in linear motion, you can calculate velocity by dividing the change in position by the change in time. In rotational motion, velocity can be found by dividing the change in angular position by the change in time.
What is wave length error?
it can be illustrated by the Heisenberg's uncertainty principle,that says that,it's almost impossible to determine the exact velocity & position of a moving electron.
How is position and velocity related?
Velocity is the rate of change of position over time.
Where the location of electron?
There is no exact location of the electron. The electron is outside the nucleus orbiting the center of the atom. You can't see it because it rotates so fast and is so small. So we can't indicate the exact location of the electron.
