C1.1.2	C1 Lesson 3 The Periodic Table
	a	Elements in the same group in the periodic table have the same number of electrons in their highest energy level (outer electrons) and this gives them similar chemical properties.	Know that elements in the same group have similar reactions because they have identical numbers of outer electrons.
			Know that the number of outer electrons determines how an atom reacts. Atoms with eight electrons in their outer shell are unreactive, i.e. the noble gases.
	b	The elements in Group 0 of the periodic table are called the noble gases. They are unreactive because their atoms have stable arrangements of electrons	Know that noble gases have eight outer electrons except for helium, which has two.

b) The elements in Group 0 of the periodic table are called the noble gases. They are unreactive because their atoms have stable arrangements of electrons

Starter Activities

Transition Metals

Activities to introduce new ideas

• Read and present sections of this article to the rest of the class. Divide into sections and each group summarises one paragraph on a poster. They can use as many diagrams as they like but a limited number of words. (Higher ability)
• Watch a few videos about the noble gases from the periodic table of videos

Activities to practice applying new knowledge

• Progress check
• Progress check answers
• end of unit C1.1 questions
• [AQA end of unit C1.1 answers]
• File:Periodic table crossword2.doc
• File:Periodic table crossword.doc

Practical activities

Demonstrations

• Demonstrate reactions of Alkali metals to show trends in chemical properties.

Class practicals

• No class practicals have been added to this lesson plan

Links

• A you tube channel with a video for each of the elements in the periodic table. Produced by the chemistry department at Nottingham university. Their website is easier to navigate(huge potential particularly for higher and triple students)
• Interactive Periodic Table that allows you to display trends in properties as graphs from RSC. [1]
• Periodic Table with animations for each element from RSC. [2]
