The electron configuration for an O2- ion is 1s22s22p6 just like the noble gas neon.
An atom in which an electron has moved up to a higher level is in an excited state. The lowest state of the atom is called the ground state.Ê
In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
There are many elements among the transitional elements which has the electron configuration differed than predicted. Such element with the lowest atomic number is chromium.
It is the energy required to remove the 1st electron from the atom
when something is in the ground^No. That is totally incorrect.Basically, a ground state electron is when the atom/element is not being surged through with heat or electricity. Basically, it's the atom's normal electron configuration. So NA [Sodium]'s ground state would be shown as : 1s2, 2s2, 2p6, 3s1.The opposite is when it's in it's excited state. You can remember tell when an atom is in it's excited state when in the electron configuration, there is a huge jump, like 1s2,2s2,2p5, 3s2. This might have happened due to being exposed to heat and or electricity.In other words, ground state=normal, excited is, well, excited. XD

The set of numbers that shows the arrangement of electrons in their shells is known as the electron configuration. It is based on the principle that electrons fill the lowest energy levels first before moving to higher energy levels. The electron configuration is typically represented by a series of numbers and letters indicating the number of electrons in each energy level and orbital.
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).
The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
Boron. It's electron configuration is 1s22s22p1.
Hydrogen atom = 1 proton 1 electron Hydrogen's 1 electron occupies the lowest energy level, 1s orbital. The atom is therefore in its "ground state". When a photon of correct frequency "collides" with a electron in hydrogen's 1s orbital the energy contained in the photon is transferred to the electron. The electron then gets added energy, so it is at a higher energy state. When it reaches this higher energy state the electron jumps to the next energy level and there it starts its new orbit. Hydrogen atom is now "excited" For any other atoms it is the same thing because all atoms can undergo excitation. The only difference between hydrogen's 1 electron and other atom's many electrons is WHICH ELECTRON will be "excited"
Yes, while nature will always try to place electrons in their lowest energy configuration, electrons can temporarily occupy higher energy states. When they fall back to the lowest energy state, the difference in energy is released as light - "a photon". Different colors of light reflect differing energy state jumps made by electrons.
A ground state is an outer orbital electron of an element that is at its lowest possible energy level. The electron in an excited state has a higher energy level than a ground state electron. The average distance from the nucleus is greater in the excited state than in the ground state.
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
level one electron contain more energy
