2014年7月26日 · An excited state means that (typically) the valence electron has moved from its ground state orbital (i.e. lowest available energy) to some other higher energy orbital. So any electron configuration in which the last electron (again, the valence electron) is in a higher energy orbital, this element is said to be in an excited state. For example, if we look at the ground state (electrons in the ...

An excited state is an energy level of an atom, ion, or molecule in which an electron is at a higher energy level than its ground state. An electron is normally in its ground state, the lowest energy state available. After absorbing energy, it may jump from the ground state to a higher energy level, called an excited state.

2016年1月14日 · Example The ground state electron configuration of sodium is "1s"^2"2s"^2"2p"^6"3s"^1. In its excited state, the valence electron in the "3s" sublevel is promoted to the "3p" sublevel, giving the electron configuration as "1s"^2"2s"^2"2p"^6"3p"^1. This is a very unstable condition and the excited electron will drop back down to the "3s ...

2014年9月10日 · An excited state electron configuration of carbon is "1""s"^"2""2s"^1"2p"^3". This is the state of carbon when it undergoes chemical bonding to form four covalent bonds, as in methane, "CH"_"4". However, the experimental evidence shows that all four bonds have the same energy, which can only be explained by the concept that the 2s and 2p ...

2017年6月3日 · So, Electronic Configuration after becoming a univalent ion (Al^+): 1s^2 2s^2 2p^6 3s^2 [3p shell is empty now.] Electronic Configuration after becoming a bivalent ion (Al^(2+)): 1s^2 2s^2 2p^6 3s^1 Electronic Configuration after becoming a trivalent ion (Al^(3+)): 1s^2 2s^2 2p^6 [Now 3s is empty] The Most Excited State here is the third one.

2023年11月21日 · The excited state can commonly take the form of the electron jumping from its original energy level or orbital, also known as the ground state, to an empty orbital of a higher energy shell that is ...

2017年6月4日 · Still magnesium In chemistry, excited state means that an electron from an orbital absorbs incoming radiation or a photon that corresponds to its energy level and hence is elevated to a higher energy level. Hence, when an element is excited, only electrons are concerned, thus not affecting the identity of the element. In order for an element to transmute or decay into another element, such as ...

2016年10月23日 · Phosphorus has atomic number 15. As such its electronic configuration in ground state is 1s^2 2s^2 2p^6 3s^2 3p^3 The following electronic configurations could be excited states 1s^2 2s^2 2p^6 3s^1 3p^4 Here one of 3s electrons has been promoted to 3p sub level 1s^2 2s^2 2p^6 3s^2 3p^2 3d^1 Here one of 3p electrons has been promoted to 3d sub level 1s^2 2s^2 2p^6 3s^2 3p^2 4s^1 Another ...

2017年8月2日 · Well, the ground-state electron configuration of "Sc" is [Ar] 3d^1 4s^2 "Sc" has many excited states, but let's choose an intuitive one... one where a valence electron is promoted to a clearly higher energy level. We'll assume the 4s -> 4p transition. That would give one of the excited states as: [Ar] 3d^1 4s^color(red)(2) -> barul(|stackrel(" ")(" "[Ar] 3d^1 4s^1 4p^color(red)(1)" ")|) (There ...
