As electrons move out of the valence shell into higher orbits they have energy to release. As they fall back down, giving off a photon, they tell the quantity of energy released by the color they give off.
Energy levels or orbital
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
Magnesium (Mg) has two electrons in it's lowest (s) orbital.
It depends on the ground level and its orbital axes
Shell or energy level corresponds to the shell in which the electrons are present.
Electrons fill orbitals in order of increasing orbital energy. The exact order of these energy levels is shown at the related link below.
No, according to Hund's rule the electrons fill the lowest orbital first and foremost and then go on to fill higher orbitals.
There is technically a 9i orbital, but no atom in the ground state has any electrons in this orbital (in fact, no known element has any electrons in even the 8s orbital, and there are quite a few energy levels between that and 9i). In an excited state ... sure, it could happen.
when we say the total number of electrons is expressed by 2n2 it means that the first orbital should have 2 electrons and the second is 8 electrons etc, on the other hand the binding energy of these electrons with nucleus is not the same for all electrons , it is calculated by the formula (2n-1) ie the orbital K in one energy level , and for the second L should be 3 energy level LI LII LIII and for the third M should be 5 energy levels MI MII MIII MIV MV etc
Electrons orbit around the nucleus in an atom at different levels. The space between each level is referred to as an orbital.
The electrons have different energy levels.
The principal quantum number describes the size of the orbital. Because they have opposite electrical charges, electrons MORE.
