When an electron moves from a higher energy level in an atom...

Key Concepts

Quantized Energy Levels

Quantized energy levels are the discrete energy states that electrons can occupy in an atom. Unlike continuous energy variations, these levels are fixed, and transitions between them result in the emission or absorption of energy in specific, quantized amounts, which is fundamental to atomic physics.

Electron Transitions

Electron transitions refer to the process where an electron moves between discrete energy levels within an atom. When an electron transitions from a higher energy level to a lower energy level, it loses energy, and this process is governed by the principles of quantum mechanics.

Photon Emission

Photon emission is the phenomenon where a particle of light (a photon) is released as an electron loses energy during its transition from a higher to a lower energy level. The energy of the emitted photon corresponds to the difference in energy between the two levels, which is a key concept in understanding atomic spectra.

00:10 So hello guys, let's go into problem 10.

00:16 When an election moves from a higher energy level in an atom to a lower energy level, a, a continual spectrum is emitted, b, a photon is emitted, c, a photon is absorbed, d, a red shifted spectrum is emitted.

00:32 And so, yeah, let's go.

00:35 So we have two lines representing two energy levels.

00:46 Two lines representing two energy levels.

00:48 Correct.

00:49 And the same is the electron moves from a higher energy level to a lower energy level.

00:55 So let's say we have the energy level of here as five.

00:59 So e is equal to five and e right here.

01:12 The energy level of this middle line is.

01:14 At 4 and the energy level of this last line is at 3 so the question says election moves from a high energy level to a lower energy level so the election let's see we have this guy right here and e decides to leave from this to here so travels all the way from energy level 5 to energy level e so basically the question is action us what happens or how how do we know that this electron has moved from a high energy level to a lower energy level? and so all of us to recall a time when your mood changed while your mood was, let's say your mood became better or your mood reduced or your mood drastically declined.

02:17 Yeah.

02:18 So basically in the increase, you must have probably heard a...

02:25 Good news or rather you must have been told oh yeah we're heading out to get you a new phone or something and in the decrease you must have received some bad news and something must let's say uh you you broke an ankle or you broke a leg so basically that is a bad news and a part of you as been diminished or not in this sense not permanently but just for a short period of time so yeah, in this sense, in order for the electrons to notify or to enable us understand that they have actually become sudden, because in this sense, i'm using the mode as an explanation.

03:07 The electrons moved from higher energy level...
