Pupil outcome: I can identify and describe properties of some different groups of elements in the periodic table. Key learning points: - Each column of the periodic table is called a group, and each row is called a period. - The periodic...

Pupil outcome: I can describe the pattern in the reactivity of Group 1 metals with water and Group 2 metals with dilute acid, and compare the reactivity of the two groups. Key learning points: - The properties of elements in each group...

Pupil outcome: I can describe the properties of the noble gases, their uses, and explain why they are unreactive. Key learning points: - Noble gases are in Group 0 of the periodic table and are unreactive. - Noble gases are all gases at...

Imperfections in solids are irregularities or deviations from the ideal arrangement of atoms or molecules in a crystalline solid structure. These defects can occur during the crystallization process when the rate of crystal formation is...

Studying Non-Crystalline Materials

A substance that lacks a regular and ordered arrangement of its constituent particles is referred to as an amorphous solid. Amorphous solids include things like proteins, plastics, glass,...

Crystalline solids consist of substances with their constituents arranged in a precise and organized manner. A wide variety of naturally occurring solid substances can be found in...

When strontium chloride (SrCl2) is added to molten sodium chloride (NaCl), it introduces impurity defects in the NaCl crystal structure. Sr2+ ions from SrCl2 replace Na+ ions in the NaCl crystal lattice, occupying sites normally occupied...

A black body is a theoretical or imaginary object that perfectly absorbs all incoming electromagnetic radiation, and also emits radiation, like heat and visible light, based on its temperature. A black body is considered theoretical...

We look at how different materials change when they are exposed to liquid nitrogen. Flowers become frozen and stiff and the petals snap. A banana hardens and is strong enough to be used as a hammer and a squash ball becomes very brittle...

We examine the different properties of iron and sulfur when they are mixed and when they are chemically combined. When iron and sulfur are mixed they retain their individual properties. When they react chemically to form iron sulfide...
