Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

If there is one half-remembered chemical fact that most of us carry from our schooldays, it is that the inert or “noble” gases do not react. The early history of these elements, ranged in the ...

New findings are set to revolutionize the entire chemistry of magnesium. The research team have discovered magnesium, which usually has a double positive charge in chemical compounds, in the elemental ...

Changing the chemistry of a compound is difficult by itself, but modifying materials only a few atoms thick is its own challenge. A group of University of Chicago scientists announced an innovative ...

Temperature programmed oxidation (TPO) is a material characterization process that heats a sample of an element or compound, then, in the thermal excitation that takes place it can establish the ...
