What state is an atom in which an electron has moved to a higher energy level?

An atom in which an electron has moved to a higher energy level is in an excited state. This can happen when the electron absorbs energy from its surroundings, such as from light or heat. The electron will eventually return to its original energy level, releasing the absorbed energy as light.


What is difference between a ground state electrons configuration and an excited state configuration?

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).


What is electron configuration of H2SO4?

The electron configuration of sulfur (S) in H2SO4 is 1s2 2s2 2p6 3s2 3p4. This is because sulfur has 16 electrons and the electron configuration follows the rules of filling orbitals from the lowest energy level to the highest.


What elements have the highest and lowest ionization energy?

Helium has the highest ionization energy due to its stable electron configuration, requiring a lot of energy to remove an electron. In contrast, francium has the lowest ionization energy because it is the least electronegative element and its outer electron is the furthest from the nucleus, making it easier to remove.


An atom is in an excited state when it has its lowest energy?

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

Is the electron configuration of sodium an excited state or ground state?

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.


When you say an electron is in its ground state what does that mean?

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

What is the difference between the ground state of an atom and excited state of an atom?

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.


What is the lowest energy state of an unbonded atom called?

Excited State -_-


When an electron jumps to a higher level is the atom is in ground state?

No, when an electron jumps to a higher energy level, the atom is said to be in an excited state. The ground state of an atom is when its electrons occupy the lowest possible energy levels.


What is the set of numbers that shows the arrangement of electrons in their shells?

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.


What states that an electron occupies the lowest energy orbital that can receive it?

The principle that states an electron occupies the lowest energy orbital available is known as the Aufbau principle. According to this principle, electrons fill atomic orbitals in order of increasing energy levels, starting from the lowest energy level. This process continues until all the electrons are placed in the available orbitals, ensuring that the most stable electron configuration is achieved.
