Question

What statement correctly describe an electron when it emits light from an atom? The electron absorbs energy and moves from a higher to lower n value. The electron emits energy and moves from a lower to higher n value. The electron absorbs energy and moves from a lower to higher n value. The electron emits energy and moves from a higher to lower n value. An atomic orbital represents... The position of hundreds of electrons in an atom at a certain point in time. All the positions that a single electron takes in a certain period of time. The most probable position of an electron in an atom. The space where a specific electron will always be found in atom. What correctly describes the relationship between the spectrum of one atom and the spectrum of another? The spectra are similar; however, the lines are offset by a certain wavelength either to higher or lower wavelengths due to the number of protons in the nucleus of the atoms. The number of visible spectral lines are identical for atoms; however, they have unique wavelengths. The visible spectral lines for an element are unique and show no relationship to the spectra for atoms of other elements. The visible lines are identical for all atoms; however, their intensities vary due to the electronic structure of the atom.

Explanation / Answer

Ans-1)
In an atom electrons are arranged in increasing order of energy.
Electrons in Higher energy level are higher in energy than that of in lower energy level.
When a electron emits light i.e. light energy it means it loses the energy and falls to lower energy level from it's own level (to which we can say higher energy level comparitively)
Hence,
Option-(D)When light emits from an atom The electron emits energy and moves from higher to lower level.

Ans-2)
An atomic orbital represents the most probable position of an electron in an atom.

Option-C.
On solving Schrodinger equation we get the shape of an orbital.
