Source sentences:
text: The only lighter metals are the metals of groups 1 and 2, which apart from beryllium and magnesium are too reactive for structural use (and beryllium is very toxic).
text: Metals in the fourth class are so unreactive they are essentially inert at room temperature.
text: Since metals that are reactive form oxides that are stable, some metal oxides must be electrolyzed to be reduced.
text: The first alloys, bronze and brass, were used for thousands of years, along with lead alloys, pewter and others—but these were all made from metals that were fairly non-reactive and could be smelted over open flames.
text: The metal is extremely reactive and pyrophoric, reacting with water even at−116
text: The most active metals are so reactive that they readily combine with the O 2 and H 2 O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil.
text: : Metals are very reactive, some more than others, but most form compounds with other elements quite easily.
