All cards with the same ‘property’ lie in the same group and by increasing number, just like elements in the periodic table. Their nuclei are not stable and they radioactively decay very quickly back into other lighter elements like the ones from which they were formed. Mendeleev was certain that each group (column) in the periodic table must contain elements that share properties, just like the ones your students have discovered, and so he left gaps for elements that had not yet been discovered.

Very soon the missing cards will be identified and you can carry out a big reveal (for example by keeping the cards in a sealed envelope until the end of the activity). Technology and Innovation Magazine Order now! The resources have been carefully selected to complement the AQA KS3 Science specifications but would be suitable for any scheme of work. For example, group 0 contains the noble gases, which are unreactive and have very low melting points. Ask students to write a summary of the expected properties of the elements that are missing.

Registered in England and Wales No. In the main activities students investigate the properties of elements and deduce their relative positions in the periodic table.

It also simplifies the process that Mendeleev went through to predict as yet undiscovered elements. Students are told: 1) Elements within group 2 are metals Alternatively, use the menu on the left to browse other curriculum areas and levels, or try a search.

However, the point of this exercise is to predict the elements’ properties.

Taking its inspiration from the recent discovery of new elements in the periodic table, this chemistry lesson is intended to get your students thinking about about how elements have been discovered, named and organised according to rules set by the International Union of Pure and Applied Chemistry.

[AR4] ELEMENT CARTOONS OW.LY/XNB4C This is a lesson from the atoms, elements and compounds topic. 2) Elements within group 2 react with hydrochloric acid by fizzing and giving off hydrogen gas. Begin this section by demonstrating the similar properties of elements in the same group, using the alkali metals. The aim is to let you learn about each of the elements of the periodic table by constructing a stable version of that element. As we know, the properties of elements follow a trend as you go down the group, alkali metals becoming more and more reactive for example.

Students are usually amused when I explain how the placeholder naming system works, giggling audibly when I tell them that Ununpentium (the placeholder for element 115) simply means ‘one one five-ium’. The task for students is to cooperate with each other to suggest which playing cards remain to be discovered. Chemistry Lesson Plans: Syllabus: OVERVIEW SYLLABUS. The aim of the student activity that follows is for them to identify experimentally, from a selection of substances, which two of those are elements that belong within group 2 of the periodic table.
