What is the excited state electron configuration of strontium?
What is the excited state electron configuration of strontium?
You can look at, say, the Wikipedia article on strontium , which gives the electron configuration as [Kr] 5s².
What is the ground state electron configuration for strontium?
Kr].5s2
Strontium atoms have 38 electrons and the shell structure is 2.8.18.8.2. The ground state electron configuration of ground state gaseous neutral strontium is [Kr].5s2 and the term symbol is 1S0.

What is the difference between the ground state and excited state of an atom?
The ground state describes the lowest possible energy that an atom can have. 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.
What is the electron configuration for the valence electrons in strontium do not include the configuration of the core electrons in your answer?
Strontium’s full electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6. To find its core electrons, we must separate the valence electrons (in this case, 5s2) from all of the complete principal energy level shells (the configuration of the closest noble gas).
Which element has the same ground state and excited state?
Helium which is atomic number 2 (2 protons in its nucleus) has 2 electrons in its 1s orbital, so its energy level is stable. Helium is the first of the so called noble gases. This is also the very top row of the periodic table.
What is the electron configuration of strontium in SR?
Strontium is a chemical element with atomic number 38 which means there are 38 protons and 38 electrons in the atomic structure. The chemical symbol for Strontium is Sr. Electron configuration of Strontium is [Kr] 5s2. Possible oxidation states are +2.
What is the difference between ground state and excited state?
✤ Ground state is not further classified. ✤ The state in which the electron energy levels are higher than those of the ground level. That is, not all the electrons will be in their lowest energy orbit. ✤ The excited electrons belong to levels which have energies associated with them.
What is the electron configuration of the ground state of an atom?
Ground State Electron Configuration : 1s 22s 22p 63s 23p 3. The ‘3s’ orbit consists of two and the ‘3d’ orbit consists of zero electrons when the atom is in its ground state. Excited State Electron Configuration : 1s 22s 22p 63s 13p 33d 1. One electron from ‘3s’ orbit moves to the ‘3d’ orbit in its excited state.
What is the excited state of an atom?
What is Excited State. Excited state of an atom refers to the state which has a higher energy than the ground state of that atom. Here, one or more electrons are not at their lowest possible energy level.
