What is the speed of an electron in motion?
The speed of an electron in motion can vary, but typically ranges from about 1 to 10 of the speed of light, which is approximately 186,282 miles per second.
What is random molecular motion?
Random molecular motion refers to the constant, unpredictable movement of molecules due to their thermal energy. This motion occurs in all substances, and the speed and direction of the molecules change rapidly as they collide with each other and their surroundings. It is this random motion that contributes to various macroscopic properties of matter, such as diffusion and viscosity.
What is the difference between the previous models of the atom and the quantum mechanical model?
The previous models of the atom, such as the Bohr and Rutherford models, described the atom as a miniature solar system with electrons orbiting around a nucleus. In contrast, the quantum mechanical model views electrons as existing in "clouds" of probability known as orbitals, where the exact location of an electron cannot be pinpointed but rather described in terms of probabilities. The quantum mechanical model also accounts for the wave-particle duality of electrons and incorporates principles of quantum physics.
What are 5 keywords for particles?
Tiny, Identical, Spaces, Motion and Attraction.
What is random motion with an example?
Random motion is the unpredictable movement of particles in a fluid or gas due to collisions with surrounding molecules. An example is the Brownian motion of pollen grains or smoke particles in air, which move in a zigzag pattern as they are bombarded by molecules in the air.
Why don't scientist use physical models to describe or explain electron motion?
Electron motion is a perfect example of how quirky quantum science is. When not being observed, an electron acts like a wave of energy. When being observed, it acts like a particle. So scientists describe the location of an electron as a probability.
Is molecular motion ordered and predictable?
No, molecular motion is generally random and chaotic. While certain patterns of motion can be observed in larger systems, such as in crystal structures, on a molecular level, individual molecules move in unpredictable ways due to constant collisions and interactions with other molecules.
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.
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 is the speed of an electron in motion?
The speed of an electron in motion can vary, but typically ranges from about 1 to 10 of the speed of light, which is approximately 186,282 miles per second.
What are some analogies for electron models?
For an electron cloud model, the analogy would be the propeller blades on a plane.
How does an electron move in an electric field and what factors influence its motion?
An electron moves in an electric field by experiencing a force that causes it to accelerate in the direction of the field. Factors that influence its motion include the strength of the electric field, the charge of the electron, and any other forces acting on the electron.
Definition of variable motion?
Variable motion refers to an object or system that changes its speed or direction over time. It can involve acceleration, deceleration, or changes in velocity, making the motion unpredictable or non-constant.
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.
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 random molecular motion?
Random molecular motion refers to the constant, unpredictable movement of molecules due to their thermal energy. This motion occurs in all substances, and the speed and direction of the molecules change rapidly as they collide with each other and their surroundings.

What will happen to the electron if a live wire is cut into two?
electron motion stops in one part , the other part is not affected
