Key Concepts

Electron Shell Models

An electron shell model is a diagrammatic representation of an atom that depicts electrons arranged in concentric shells around the nucleus. These models help in visualizing the organization of electrons into various energy levels, particularly highlighting the valence shell where chemical bonding and reactions take place.

Valence Electrons

Valence electrons are the electrons located in the outermost shell of an atom and are key to an atom’s chemical reactivity. Their arrangement and number determine how an atom interacts with others, playing a crucial role in the formation of bonds and in processes such as oxidation and reduction.

Oxidation and Electron Transfer

Oxidation involves the process where an atom loses electrons, often during a chemical reaction involving electron transfer to another atom. This concept is fundamental to understanding redox reactions, where electron movements alter the oxidation state of atoms, leading to the formation of new compounds, such as when silicon is oxidized to form silicon oxide.

00:01 In problem 5, draw shell model of silicon and oxygen atom to show transfer of electron during oxidation.

00:07 So when silicon combined with oxygen, then it will form silicon dioxide, which is sio2.

00:12 So silicon having atomic number is 14.

00:16 So we can write it as 2, 8 and 4.

00:19 So that means there are 4 valence electrons.

00:24 4 valence electron present in the silicon.

00:28 And in case of oxygen atmic number is 8 and we can write it as 2 and 6 so that mean we can say 6 valence electron present in the oxygen atom present in oxygen atom so we can make the shell model to understand much better about the about this so this is the nucleus and there are 3 shell in case of silicon so we can make it as 1 this is the second shell and this is the third shell so this is the case of the silicon so this is the case of the silicon atom because three shell present in case of silicon so now we can make oxygen so this is the nucleus of oxygen so this is the first shell and this is the second shell of the oxygen and this is the nucleus and this is the first shell of oxygen and this is the second shell of the oxygen atom.

01:37 So that means this is for oxygen.

01:39 This is for silicon and this is for the oxygen.

01:42 Now we can put the electron in these shells.

01:45 So there are two electrons in the inner shell of the oxygen and six electron in the out shell of the oxygen.

01:53 So 1, 2, 3, 4, 5 and 6.

01:57 So here also 1, 2, and this is 1, 2, 3, 4, 5 and 6.

02:06 So now we can put the electrons in silicon also.

02:12 So this is the inner shell which contained 2 electron.

02:17 And in the second shell, it contained 8 electrons.

02:19 So 1, 2, 3, 4, 5, 6, 7 and 8.

02:27 Because in the second shell of silicon contain 8 electron and in the third shell it contained 4 electrons so 1 2 3 and 4 now what is going to happen during this oxidation so basically this silicon can lose its electrons so we can make in this way like this okay so what is going to happen in this case so basically silicon can lose electron so that means this can low silicon and oxygen atom gain electron in this case so that means we can see this so this is the silicon and this is the case of the oxygen atom nucleus this is the case of other oxygen atom nucleus so this is the first shell of silicon this is the second shell of the silicon and this is the third shell of the silicon atom and this is the first shell of and this is the second shell of the oxygen atom and this is the first shell of the oxygen atom and this is the second shell of the oxygen atom so that means this is oxygen atom this is again oxygen and this is the case of silicon atom so now when transfer of electron can take place so now when transfer of electron can take place we can see this the inner shell of the silicon contains two electrons that already present and in the second shell it contains 8 electrons so that means 1 2 3 4 5 6 7 and 8 but in case of the 3rd shell because the electrons are transfer now so in the 3rd shell there is no electron present in the silicon but in case of the oxygen atom inner shell contains the 2 electrons like this and like this way and in the outermost shell of the oxygen atom now see there are 1 2 3 4 6 electrons present before the transfer but when the silicon transfer it's 2 electron for 2 electrons in 1 oxygen atom and 2 electron in the other oxygen atom so that mean in the outermost shell of oxygen now contains total 8 electrons so 1 2 3 3...
