Why is 3rd shell 8 or 18?
The third shell of an atom has 18 electrons only not 8 electrons.
You might be confused because first the electrons of 4s are filled and then the 10 electrons of 3d shells are filled.
They are filled because of the n-l rule.
So after filling the 3s and 3p subshell with 8 electrons, the next shell to fill is the 4s one..
Is the ground state the most stable?
In chemistry and physics, the ground state is defined as the lowest allowed energy state of an atom, molecule, or ion. In other words, the ground state represents the most stable configuration. If there is more than one possible ground state, degenerate states are said to exist.
Is N 0 A ground state?
Ground state properties of hydrogen Just to be confusing, the subscript 0 which refers to the ground state refers to n = 1, not n = 0. The radius of an electron in the ground state of hydrogen is called the Bohr radius, named after Niels Bohr, a famous Danish physicists.

Which Orbital has the highest energy lowest energy?
The order of the electron orbital energy levels, starting from least to greatest, is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. Since electrons all have the same charge, they stay as far away as possible because of repulsion.
What is the highest energy level?
The highest occupied energy level in an atom is the electron-containing main energy level with the highest number.
What is the 2 8 8 rule in chemistry?
There is a 2-8-8 rule for these elements. The first shell is filled with 2 electrons, the second is filled with 8 electrons, and the third is filled with 8. You can see that sodium (Na) and magnesium (Mg) have a couple of extra electrons. They, like all atoms, want to be happy.
What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d3?
VanadiumAlso, if you look at the last number/letter combination, you can go directly to that spot on the periodic table to determine the element. Example: 1s2 2s2 2p6 3s2 3p6 4s2 3d3 (This has a total of 23 electrons which equals the atomic number of V – Vanadium.)
What is 1s2 2s2 2p6 3s2 3p6 4s2 3d6?
Name of Element : Iron (Ferric) Atomic Weight : 55.8. Atomic Number : 26. Group : Transition Elements. Electron Configuration: 1s2 2s2 2p6 3s2 3p6 4s2 3d6.
Why are shells named KLMN?
The names of the electron shells come from a fellow named Charles G. Barkla, a spectroscopist who studied the X-rays that are emitted by atoms when they are hit with high energy electrons. … This innermost shell is now called the K-shell, after the label used for the X-ray.
What is the lowest possible energy state?
ground stateThe ground state of a quantum-mechanical system is its lowest-energy state; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state.
Why are there 18 electrons in the third shell?
The 3rd subshell consists of an s orbital , a set of (3)p orbitals and a set of (5)d orbitals. Each orbital holds 2 electrons and you will indeed find that you can fir 18 electrons in. … This is because it is the maximum capacity of the 3rd shell and it doesn’t tell about the order in which the electrons are filled.
