Lesson: Molecules Compounds and molecules January 2022 Student Expectations 1. 2. 3. Turn off your camera. Mute your microphone (unless your teacher asks you to unmute). Engage in the lesson and only use the chat facility to ask or answer questions related to the lesson. 4. All chat is recorded and is sent to Mrs Wilson and your Head of Year at the end of each session. 5. Inappropriate behaviour will result in a phone call or a home visit during the lesson and you will be removed from the lesson by the teacher. 6. Send your work to your teacher at the end of each session Please note: if you fail to follow these expectations, you will not be able to access Dearne Home Learning and will attend school for face to face teaching.

Lesson: Compounds and molecules Understand the difference between compounds and molecules, and identify them

Lesson: Compounds and molecules Understand the difference between compounds and molecules, and identify them using particle diagrams. Compound, molecule, element, atom, particle, bond Define compound and molecule Represent compounds and molecules using particle diagrams Recognise if a molecule is an element or a compound Compare and contrast the properties of elements and compounds and give a reason for their difference

Lesson: Molecules Compounds and molecules January 2022 Suggest how molecules are formed. Include an example. You must write in full sentences and use a connective.

Lesson: Molecules Compounds and molecules January 2022 A molecule is two or more atoms

Lesson: Molecules Compounds and molecules January 2022 A molecule is two or more atoms joined together. They can be as small as 2 atoms joined together, or as large as over 1000. Most non-metals exist as small or giant molecules.

Lesson: Molecules Compounds and molecules January 2022 Molecules of elements: Oxygen is an element.

Lesson: Molecules Compounds and molecules January 2022 Molecules of elements: Oxygen is an element. All its atoms are oxygen atoms. However, the atoms do not exist separately. Instead, they pair up to form oxygen molecules (O 2). Hydrogen also has molecules with two atoms (H 2). The little number in a formula tells us how many atoms of the element there are. The number comes after the element.

Lesson: Molecules Compounds and molecules January 2022 Molecules of compounds: Compounds are made from

Lesson: Molecules Compounds and molecules January 2022 Molecules of compounds: Compounds are made from two or more atoms of different elements chemically joined together. For example, water is a compound of hydrogen and oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. We show this in its chemical formula, H 2 O. (2 x H, 1 x O) H 2 O CO 2 C 2 H 6 O

Lesson: Molecules Compounds and molecules January 2022 Molecules and compounds can be drawn as

Lesson: Molecules Compounds and molecules January 2022 Molecules and compounds can be drawn as particle models. We use circles to represent the atoms. To show them joined together, either draw them touching, or connect them with a “stick”, as seen below: H O H H H O Both are water, just drawn slightly differently

Lesson: Molecules Compounds and molecules January 2022 Draw particle diagrams for the following molecules:

Lesson: Molecules Compounds and molecules January 2022 Draw particle diagrams for the following molecules: 1. Bromine (Br 2) 2. Hydrochloric acid (HCl) 3. Hydrogen peroxide (H 2 O 2) 4. Carbon monoxide (CO) Stretch: State whether they are elements or compounds, and give a reason why.
