Electron Spin
In the classical sense, the electron was once considered to spin about its axis in the same way the earth rotates around its axis. Classical mechanics yields to quantum physics here, because the electron does not actually spin about its axis in the same the earth does. Instead, we measure the angular momentum of the electron, which is a quantum factor.
The spin of an electron is always 1/2, and can be measured and confirmed experimentally. This value is constant (although it can be said to be "up" or "down"). The scalar value of the electron spin never changes from 1/2.
Electron Orbitals
An electron travels around the nucleus in confined quantum regions, or shells. Unlike a planet that orbits the sun in a predictable elliptical orbit, an electron's trajectory within its shell is random and unpredictable. Consider a spherical cloud around the nucleus. That cloud is made up of one or two electrons, and there is a known probability that you will find an electron on any point on the surface of that shell.
As a thought experiment, if you were able to take a video of a single hydrogen atom, you would observe the nucleus at the center comprising one proton (and one neutron in deuterium), surrounded by a distant, thin opaque sphere. The sphere is not solid, it is just a single electron buzzing around the nucleus so quickly that, in the time your camera had a chance to register one frame of the image, the electron had buzzed all around the nucleus so many times that the sphere appears to you to be semi-solid.
By strict definition, only two electrons can occupy the same shell at one time, due to a phenomenon called the Pauli Exclusion Principle. In many atoms, several shells have exactly the same energy levels, and so in quantum parlance we combine shells of identical energy levels together, and consider them as a single shell. There are n2 shells with identical energy levels for each orbital number, so therefore there is 1 shell for the first orbital, 4 shells for the second orbital, 9 shells for the third orbital, and so one. Since each shell can contain no more that 2 electrons, there are 2 electrons allowed in the first orbital, 8 in the second, 18 in the third, and so on.
AnswerThe nucleus carries a positive charge and the electron carries a negative charge.Better answers are more complicated, but this should be a start.
[This answer is incorrect - spin has nothing to do with charge]
More informationWhen we talk about electron spin, lots of folks get the impression that electrons "rotate" about an "axis" in the same way the earth does to make day and night. It's not really like that. Spin is actually a quantum mechanical characteristic rather than a "physical spin" like the revolution of planetary bodies. Hey, we assign color as a quantum mechanical characteristic, but that doesn't mean that what we assign a color to actually has "color" or is a certain "color" as in being possessed of a certain hue.
What else can I help you with?
Is it true electrons gain energy as they move down the chain?
No. Electrons gain energy as they move up the chain, i.e. in more outer shells.
What are found in the electron shells or clouds?
Electrons are found in the shells and clouds.
Do atoms with many electron shells let go of their electrons easier than fewer shells?
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
What is a region around the nucleus in which electrons move about?
Electrons surround the nucleus of an atom in patterns called electron shells.
How many shells are there in element mercury?
Mercury has 80 electrons which means there are 6 shells in a neutral atom of mercury.
Particles with a negative charge that move in shells around the nucleus?
electrons
What is part of an atom that move around the outer shells?
the valence electrons
Which particles are found in shells around a nucleus?
Electrons are the particles found in shells around a nucleus. They are negatively charged and move in orbitals at specific energy levels.
As you move across a period elements have the same number of?
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
In order for the electrons to move they need a closed loop called?
electrons need a closed loop called what in order to move?
Is it true electrons gain energy as they move down the chain?
No. Electrons gain energy as they move up the chain, i.e. in more outer shells.
Location of electrons?
Electrons are found in electron shells surrounding the nucleus of an atom. They move rapidly within these shells, which are composed of energy levels that determine the electron's distance from the nucleus.
Where do electrons travel in a atom?
Electrons travel in specific energy levels around the nucleus of an atom. These energy levels are known as electron shells, and electrons move within these shells in a kind of "cloud" around the nucleus.
What did Niels Bohr calls the shells in which electrons move around the nucleus?
Bohr ring
Explain of where electrons might be found in atom?
Electrons are found in regions around the atomic nucleus known as electron shells or energy levels. These shells are organized based on the energy of the electrons they contain, with the innermost shells having lower energy levels and the outermost shells having higher energy levels. Within each shell, electrons move in specific orbitals or pathways.
In physical science which particles move around the nucleus of an atom?
Electrons move around the nucleus of an atom. Protons and neutrons are located in the nucleus at the center of the atom. Electrons orbit the nucleus in specific energy levels, or shells.
How Many Shells Of Electrons Does Iron Have?
iron has 4 shells because there are 30 electrons.
