What is the highest energy level of an electron?
valence shell
The outermost orbital shell of an atom is called its valence shell, and the electrons in the valence shell are valence electrons. Valence electrons are the highest energy electrons in an atom and are therefore the most reactive.
What makes an electron occupy a higher energy level?
An electron will jump to a higher energy level when excited by an external energy gain such as a large heat increase or the presence of an electrical field, or collision with another electron.
How does the spin of an electron affect its energy?
In this effect, the motion of the electron around the nucleus creates an effective magnetic field that causes spin-up electrons to have a slightly different energy from spin-down electrons. As in an atom, this motion causes one orientation of the electron spin to have lower energy than the opposite orientation.
How much energy does it take for an electron to move up an energy level?
It needs to gain (-3.4) – (-13.6) = 10.2 eV of energy to make it up to the second energy level. The electron can gain the energy it needs by absorbing light. If the electron jumps from the second energy level down to the first energy level, it must give off some energy by emitting light.
What is the maximum number of electrons that can occupy an orbital?
two electrons
In other words, an orbital is an area where the electrons live. There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max.
What is the maximum number of electrons that can occupy each of the first five principal energy levels?
2 electrons
A. Energy Levels Each principal energy level can contain up to 2n2 electrons, where n is the number of the level. Thus, the first level can contain up to 2 electrons, 2(12) = 2; the second up to 8 electrons, 2(22) = 8; the third up to 18, 2(32) = 18; and so on.
What is the magnitude of the electron spin?
The square of the magnitude of the electron’s spin is S2 = s(s + 1)ħ2 = 3/4ħ2. The spin quantum number s for the electron is equal to ½. The spin angular momentum of an electron, measured along any particular direction, can only take on the values ħ/2 or -ħ/2.
Does spin increase energy?
There is nothing rotating in the electron which is assigned spin 1/2, so in this sense there is no energy associated with spin the way that there is energy associated with angular momentum.
How do you calculate the energy needed to move an electron?
Re: Calculate energy required to remove an electron 1) Calculate the electron’s kinetic energy using E(k) = 1/2 mv^2. This is the ‘excess’ energy. 2) electron’s kinetic energy + sodium’s work function (per atom) = energy of incoming photon.
What is the energy required to move an electron?
ionization energy, also called ionization potential, in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule.
