What is the amount of energy required to move an electron from one level to another called?; Is the amount of energy required to move an electron?; How does an electron move between energy levels?; What is an energy orbital?
The term "quantum" refers to the amount of energy needed to move an electron from one energy level to the next higher one.
It also applies here when it comes to moving electrons between levels because it refers to the smallest amount of energy required to do anything. It is a part of quantum physics, which deals with quantum theory and studies levels at which things are molecular, atomic, and subatomic.
A process known as absorption occurs when an atom transitions from its ground state to an excited state by absorbing energy from its surroundings. The electron takes in the energy and advances to a higher level of energy. By dissipating the extra energy it took in during the emission process, the electron returns to the ground state.
The energy of orbitals is the energy required to move an electron from one orbital to another or the energy released when an electron is added from another orbital.

Amino acids are colourless compounds. In order to see the spots on the chromatogram, you will apply a solution of ninhydrin to the paper. Ninhydrin will react with the amino acid to produce a purple compound. Silica gel will serve as the stationary phase in the thin layer chromatography procedures.
Ninhydrin (or fluorescamine) is very useful in chromatographic methods for the analysis of amino acids. One of these is paper chromatography, wherein amino acids are separated as the consequence of differences in their partition coefficients between water and an organic solvent. The aqueous phase is held stationary in the pores of the paper because of strong interaction of the water with the hydroxyl functions of the cellulose. The differences in partition coefficients show up as differences in rates of migration on the surface of moist (but not wet) paper over which there is a slow flow of a water-saturated organic solvent.

Increasing electronegativity for the following chemical would be: Florine > Carbon > Boron > Aluminum > Calsium > Cesium > Barium.
When atoms can attract electrons during chemical bonding, they are said to be electronegativity.
Electronegativity rises from left to right across the periodic table. The reason for this is that as the atomic number rises, there are more protons. Due to the growing size of the atoms, electronegativity decreases from top to bottom. As a result, fluorine is regarded as the element with the highest electronegative potential, whereas cesium has the lowest.
