Why do the quantized energies of electrons in hydrogen atoms...

Key Concepts

Quantum Energy Levels

Quantum energy levels refer to the fixed, discrete values of energy that electrons can occupy in an atom. This quantization emerges from the solutions of the Schrödinger equation, which dictate that electrons exist in specific, non-continuous states, rather than any arbitrary energy level.

Electronic Transitions

Electronic transitions are the processes by which electrons move between different energy levels within an atom. When an electron transitions from a higher to a lower energy level, it emits a photon whose energy corresponds exactly to the difference between those levels, leading to distinct spectral lines.

Emission Spectra

Emission spectra are the patterns of light produced when electrons in atoms change energy levels, emitting photons at specific frequencies. Because the energy levels are quantized, only photons of particular energies (and thus frequencies) are emitted, resulting in a series of individual spectral lines rather than a continuous spectrum.

00:01 In this video, we are going to focus on finding out that why quantized energy of electrons in hydrogen atom gives us emission spectra comprised of individual lines at certain frequencies.

00:12 So firstly, we will understand that bohr postulated and it will be here p -o -s -t -u -l -a -t -e -d.

00:20 And then here we can write that he postulated that the energies of an electron in the atom and it will be here energy.

00:30 Of an electron and then here we can say is quantized and let us first write q -u -a -n -t -i -z -e -d and then here we can say that it results as a transition from higher level to lower levels.

00:51 So that very thing can also be written over here as transitions from higher level and then then here we can write to lower level.

01:02 So it will be here, let us write it as such.

01:07 So hence, if we have understood till now, then we can say that let us understand with the help of a figure.

01:15 So suppose this is a level of, we can say this is a higher level.

01:20 And then here we can draw another one and it will look like this.

01:23 So whenever an electron jumps from higher level to lower level, then in that case, it releases some frequency, right? and here we must understand that every possible jump of an electron from one energy state to another result in a different line of hydrogen spectrum.

01:46 So it can be here said that different lines in hydrogen spectrum, and it will be here, h -y -d -r -o -g -e -n, and then here we can say spectrum for every possible jump.

02:03 And it will be here for every, and then here we can write a possible jump...
