step 1 So let's discuss the design question. That is write lavis formulas for each of the following. So

Key Concepts

Ionic Bonding

Ionic bonding is a type of chemical bonding that occurs when one or more electrons are transferred from one atom to another, resulting in the formation of oppositely charged ions. These ions are held together by strong electrostatic forces. In Lewis formulas for ionic compounds, it is common to indicate atoms as ions (cations with a positive charge and anions with a negative charge) to reflect the electron transfer that has taken place.

Octet Rule

The octet rule is a chemical guideline that atoms tend to form bonds in such a way that each atom has eight electrons in its valence shell, achieving a noble gas electron configuration. This principle is commonly used when drawing Lewis structures to determine the number of electrons an atom needs to be surrounded by for stability, either through sharing electrons in covalent bonds or through complete transfer in ionic bonds.

Lewis Structures

Lewis structures are diagrams that represent the bonding between atoms in a molecule and the lone pairs of electrons that may exist. These structures use dots to depict electrons around atoms, allowing for a visual representation of how electrons are distributed in simple molecules or ions. They help in understanding the arrangement of electrons that enables atoms to achieve a more stable (often octet) configuration through covalent or ionic interactions.

Transcript

00:01 So let's discuss the design question.

00:03 That is write lavis formulas for each of the following.

00:08 So we have to write levis formula formulas for the following compounds here.

00:20 That is sodium iodide.

00:24 Sodium iodide levy formula is sodium n -a -i.

00:33 So this is metal, this is non -metal.

00:35 And here electronic structure is sodium having one electron in the outermost shell and iodine having seven electrons so this will lose electron sodium will lose electron and this will gain electron this will gain electron and it will have negative charge and it will have positive charge.

01:08 So this is the level structure.

01:11 We can further add sodium positive and iodine negative charge.

01:21 And next in part b we have is potassium sulfite.

01:28 K2 as is the levis formula for potassium sulfide.

01:33 Potassium is metal, sulfur is non -metal and it will form here.

01:38 Sulfur will central element and bound with potassium.

01:44 So here, for a sulfur will gain two electrons and potassium will lose.

01:51 And potassium will lose one, one, each potassium lose one electron.

01:55 So here, this is having six outermost electron and this will has one and this has one electron.

02:03 This will lose electron...
