Actually, its more of a matter of why don't they fall into the nucleus and stop moving. You see, electrons are very chaotic particles that always move around because of the kinetic energy (kinetic energy is the energy of a moving object) they carry, and at a subatomic scale it is very difficult, and practically impossible, to "stop" a particle i.e. reduce its kinetic energy to zero. So you see, when electrons are bound by electrostatic forces to atomic nuclei, they can't fly away because of the attraction between the protons of the nucleus and them, but they also can't just stick to said nuclei because they still have kinetic energy which keeps them moving.
A simple analogy is spinning a string with a small stone tied to the opposing end. The stone spins around the opposite end of the string because it is bound to that point by the string, but it can't fall towards it because it has a lot of kinetic energy that's trying to make it fly away.
Hope this was useful.
What else can I help you with?
How magnetic moment originate from motion of electron?
Electrons revolve around the nucleus. A revolving electron is equivalent to a current loop. Hence, it produces a magnetic moment.
What particles move around the nucleus in constant and random motion?
Electrons are the particles that move around the nucleus in constant and random motion.
What shows the development of atomic models in chronological order?
The development of atomic models in chronological order is as follows: Atoms are solid spheres. Atoms have electrons attached to their surface. Electrons move around nucleus at specific energy levels. Rapid motion of electrons around nucleus in a cloud.
How do scientists currently describe the movement of electrons around the nucleus?
The short answer is the motion is completely deterministic, but not predictable in the everyday, macroscopic sense. The more accurately you try to measure momentum of the electron in transit, the less you will know about its position.
Which force field can accelerate an electron but never change its speed?
I would say a magnetic field. When an electron enters a magnetic field that is oriented perpendicular to its path of travel it causes the electron to loop in a circle. While the speed stays the same the velocity is constantly changing due to the circular motion. Hence same speed but undergoing an acceleration.
What keep the electron in motion around the nucleus to which it is attracted?
the inter nuclear force of attraction between the nucleus and electron keep it moving in a circular manner around the nucleus
What subatomic particle is in constant motion around the nucleus?
Electrons are the subatomic particles in constant motion around the nucleus of an atom. They orbit the nucleus in energy levels or shells.
Where does the electron in a stationary atom gets energy for its rotatory as well as spin motion?
Motion: Usually from the ambient matter in the form of heat. If the ambient matter is cooler than the atom, the motion will slow down, and if it's warmer, the electron will accelerate. Rotation: The electron is negatively charged and the nucleus is positively charged. Because of this, the electron is magnetically attracted to the nucleus, so the motion will be concentrated around it.
Why are electron always moves around the nucleus?
Due to Uniform Circular Motion.
What are the two types of motion that the electrons of an atom exhibit?
The two types of motion that electrons exhibit in an atom are orbital motion around the nucleus, and spin motion on their own axis. Orbital motion refers to the movement of electrons in specific energy levels around the nucleus, while spin motion refers to the clockwise or counterclockwise rotation of an electron on its axis.
What did BOHR assume about the motion of the electron?
Bohr proposed that an electron is found only in specific circular paths, or orbits, around the nucleus.
How centripetal force balances n circular motion of electron?
the centripetal force along with the attractive force of the electron on the nucleus are balanced by a phenomnon known as the strong nuclear force which prevents the electron from coliding with the nucleus
What is the orbital angular momentum of an electron in the orbitals?
The orbital angular momentum of an electron in orbitals is a measure of its rotational motion around the nucleus. It is quantized and depends on the specific orbital the electron is in.
What did Bohr assume about motion of electrons?
Bohr proposed that an electron is found only in specific circular paths, or orbits, around the nucleus.
Is there any force acting on an electron?
The answer simply depends on the environment that the electron is in. If the electron is in orbit around the nucleus of an atom then there will be a strong electromagnetic force acting on the electron towards the nucleus.
What energy relations exists within the atom as electrons revolve about the positive nucleus?
there is a force of attraction between the positive nucleus and each negative electrons, and this force is counterbalanced by one that is determined by the orbital motion of the electron.
What two kinds of electron motion are important in determining the magnetic property of a material?
The two main types of electron motion that are important in determining the magnetic property of a material are spin motion and orbital motion. Spin motion refers to the intrinsic angular momentum of an electron, giving rise to its magnetic moment, while orbital motion refers to the movement of electrons around the nucleus within an atom, contributing to the overall magnetic behavior of the material.
