1s2 2s2 2p6
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
The groundstate for Sodium (11-Na) is: 1S2 , 2S2, 2P6, 3S1 If you count the ^powers you notice it'll sum to 11, when Sodium is excited the outermost electron (3S1) will be excited from the 3S shell to the next shell up which is the 3P shell. The "core" electron configuration doesn't change so the first excited state is simply: 1S2 , 2S2, 2P6, 3P1 For the next excited state the electron that is now in the 3P shell will transition to the 4S shell before the 3D shell
The element with the excited state of 1s22s22p33s1 is sodium. In its ground state, sodium has the electron configuration 1s22s22p63s1, but in the excited state, one of the electrons from the 3s orbital is promoted to a higher energy level in the 3p orbital.
The electron configuration of copper at an excited state is [Ar] 3d104s1. In the excited state, one of the 4s electrons is promoted to the 3d orbital to achieve a half-filled d orbital, which is a more stable configuration.
The electron configuration of sulfur in the excited state is [Ne] 3s2 3p4, rather than the ground state configuration of [Ne] 3s2 3p4. In the excited state, an electron has moved from the 3p orbital to a higher energy level.
The electron configuration of aluminum in the excited state is 1s2 2s2 2p6 3s2 3p1. In its ground state, aluminum has an electron configuration of 1s2 2s2 2p6 3s2 3p1. By exciting an electron to a higher energy level, such as from 3p1 to 3s1, the electron configuration changes in the excited state.
The electron configuration of a sulfur atom in its ground state is 1s2 2s2 2p6 3s2 3p4. In an excited state, one of the electrons can be promoted to a higher energy level. For example, in an excited state, the electron configuration of a sulfur atom could be 1s2 2s2 2p6 3s1 3p5.
No, 2-8-7 does not indicate an excited state. It typically represents the electron configuration of an element in its ground state, specifically for nitrogen. An excited state would involve the electrons being in higher energy levels than the ground state configuration.
The electron configuration of calcium in its ground state is 1s2 2s2 2p6 3s2 3p6 4s2. In its excited state, one or more electrons transition to higher energy levels. For example, one possible excited state electron configuration for calcium could be 1s2 2s2 2p6 3s2 3p6 4s1 3d1.
The most likely electron configuration for a sodium ion (Na+) in its ground state is 1s2 2s2 2p6. This configuration represents the electronic structure of a sodium atom that has lost one electron to become a sodium ion, achieving a stable octet configuration similar to that of a noble gas.
The electron configuration of nitrogen in its ground state is 1s^2 2s^2 2p^3. In an excited state, one of the electrons can be promoted to a higher energy level. For example, in an excited state, the electron configuration of nitrogen could be 1s^2 2s^2 2p^2 3s^1 3p^1.
There are an infinite number of excited states that fluorine's 9 electrons could be in. To write one you simply need to write out the excited state of fluorine and put one of its electrons in a higher energy orbital. F: 1s2 2s2 2p5 F*: 1s2 2s1 2p5 3s1 The latter is just one possible excited state of fluorine.
