Elements resources

Students explain the mistake in each of six sentences about elements, compounds or mixtures.

Students are given the formula of two different types of chlorophyll. Students name all the elements present, and how the number of atoms differs between the chlorophylls.

15 names of elements and symbols are provided. Students shade in those squares where the symbol correctly matches the name.

Students use diagrams to answer questions about atoms, elements, compounds, and mixtures. They are then asked to use these words to describe the differences between diagrams.

Students answer three multiple-choice questions about atoms, elements, and atomic number.

Students classify 12 common substances as either a compound, mixture, or element.

Students classify six common substances as either a solid, liquid, or a gas. Students then group these substances into elements, mixtures, or compounds.

Students use the periodic table and their own knowledge to complete the types of atoms present, and total number of atoms present for three compounds.

Students select the correct written definition of the words element, compound, and mixture.

Students label six diagrams as an element, compound, or mixture.

Using provided information students answer three multiple-choice questions about numbers of atoms, elements, molecules and compounds.

In this task, students look for patterns in electron arrangement in the periodic table. They use their ideas to place missing elements in the table, answer some questions about the patterns, and use the patterns to predict the properties of some elements.
