What is the work done by an electron revolving in a circular orbit of rdius r around the nucleus?
Here a centripetal force provided by electrostatic force of attraction acts on the electron towards the centre of orbit but motion is along the tangent to the circular orbit at ecah point. As force and displacement are in mutually perpendicular directions at each point, the work done is zero. E V SHAKKEER HUSSAIN
How is an electron's wavelength related to its speed and mass?
The wavelength of an electron is inversely proportional to its speed and directly proportional to its mass. This means that as the speed of an electron increases, its wavelength decreases, and as the mass of an electron increases, its wavelength also increases.
What is the energy of electron in first orbit?
The energy of an electron in the first orbit of a hydrogen atom is -13.6 electron volts (eV). This energy value represents the lowest energy level in the atom and is known as the ground state energy.
Where do electrons orbit?
Electrons do not orbit around the nucleus like planets around the sun. Instead, they exist in electron clouds around the nucleus, depicted as a probability distribution of where an electron is likely to be found.
What prevents an electron from being freed due to its centrifugal force?
A negatively charged electron is attracted by the positively charged nucleus so the electron revolves around the nucleus so that it can generate enough centrifugal force in order that the attractive force is nullified and the electron can stay in its orbit
What is the speed of the electron in its orbit around the nucleus?
The speed of an electron in its orbit around the nucleus is approximately 2.18 million meters per second.
What is the speed of electron in shell?
speed of electrons varies from shell to shell . it increases from inner orbit to outer orbit
Why are electron in the electron cloud?
electron cloud refers to orbit present in the atom and electron can can be revolved by the orbit only as it is an imaginary path made of energy
What is an electron orbit region around an atom?
An orbit is the path around the nucleus of an atom. an electron generally moves along this orbit.
What is meant by valency orbit and valency electron?
A valance electron is one that is associated with an atom. The valence orbit is the one that electron travels in.
What a transition from an outer orbit to an inner orbit the electron .?
When an electron moves from an outer to an inner orbit, energy is released in the form of light of a particular wavelength.
What does the wavelength of electron if it moves with the speed of light?
-- First of all, since the electron has rest mass, it can never move at the speedof light.-- Following DeBroglie, the electron's wavelength is such that an integral numberof them fit around the length of the electron's orbit when it's bound to an atom.
Number of electrons in the outer orbit of an atom of lithium?
A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
Is that electron moves with same and constant speed in orbit?
yeah but it depend on which quantum level it is and also on the state of the atom whether it is in excited or ground state.
The transition of an electron from outer orbit to inner orbit involves a change in its what?
energyy
Where is an electron in a atom?
The electron is the only thing in the atom is moving. It makes AA Eliptical Orbit around the positive charges. An Eliptical Orbit is a oval type of orbit around an object
What is it called when a orbit around a nucleus?
"electron"
