Key Concepts

Shell Model

The shell model is a way of representing the distribution of electrons around the nucleus of an atom in discrete energy levels or shells. This model helps illustrate how electrons are arranged in atoms and how they participate in chemical reactions by moving from one shell to another, particularly during processes such as oxidation.

Electron Configuration

Electron configuration describes the specific arrangement of electrons in an atom’s energy levels or orbitals. It explains how electrons fill the shells in a particular order and provides insight into an atom’s chemical properties and reactivity, including how electrons are transferred during oxidation processes.

Oxidation and Electron Transfer

Oxidation involves the loss of electrons from an atom or molecule, a process that is central to many types of chemical reactions. Understanding electron transfer during oxidation is crucial for explaining how atoms, such as metals and non-metals, form ions and subsequently engage in bonding interactions.

Ionic Bonding

Ionic bonding is the electrostatic attraction between positively charged ions and negatively charged ions that forms after electron transfer. In processes like oxidation, one atom loses electrons to form a cation while another gains electrons to form an anion, resulting in the formation of an ionic compound through these interactions.

Transcript

00:01 In problem 4, draw shell model of lithium and oxygen that show transfer of electron during oxidation.

00:08 So when lithium and oxygen combined, then it will form lithium oxide.

00:13 So lithium, which having atomic number, is 3.

00:19 So its first shell contain 2 electron and in the second shall contain 1 electron.

00:25 So that means we can say that lithium have 1 valence electron, 1 valence electron.

00:36 And lithium is a metal which can lose electron.

00:40 So on other hand, oxygen having atomic number 8.

00:46 So we can write it as 2 and 6.

00:48 So that means in the first shell of oxygen contain 2 electron and in the second shell it contains 6 electrons.

00:56 So we can say that this oxygen has 6 valence electron and oxygen is a non -metal which can gain electrons.

01:08 So in this case lithium dose electron and oxygen can gain electron in this shell model.

01:16 Now we can make a shell model to understand much better how electron lows or gain during this oxidation.

01:35 So this is basically the we can make a nucleus.

01:42 Now so this is the first shell and this is in the second shell and this is in the second.

01:53 Shell so these are the two shell and similarly this is the nucleus and this is the first shell and this is the another shell all right so this is again nucleus and this is the first shell and this is the second shell now that means this is basically for lithium this is oxygen and this is again for lithium so now we can put electron in these shells by using blue color...
