PPT-Intermolecular Forces

Chemistry 11 Ms McGrath Intermolecular Forces The forces that bond atoms to each other within a molecule are called intramolecular forces Covalent bonds and ionic bonds are an example of intramolecular forces. IB Topic 4: Bonding. Carbon allotropes. pure carbon is covalently bonded in three of different forms (allotropes). graphite. diamond. fullerenes.

Students know . the atoms and molecules in liquids move in a random pattern relative to one another because the intermolecular forces are too weak to hold the atoms or molecules in a solid form..

Draw a picture.. What is a force?. A force is a push or a pull. . Forces make objects accelerate. What are the two general types of forces? How are they different?. Type 1: Contact Forces. Force as a result of object touching. (bring notes to show me next lesson). ;. Read pages 60 – 62 in your text book. Complete the questions at the end of each double page spread.

They LOVE each other – they’re attracted to each other. They HATE each other – they repel each other. 2.
