(. melting, freezing, vaporization, condensation, sublimation. Elements in Group 1 are called . alkali metals. . lithium, sodium, potassium, rubidium, cesium, and francium . • Alkali metals are so named because they are metals that react with water to make alkaline solutions. . HL: Locate the alkali metals on the periodic table.. HL: Describe the properties of the alkali metals.. HL: Describe the reactions of the alkali metals with air.. HL: Describe the reactions of the alkali metals with water using word equations.. By 1869, there were 63 known elements. Mendeleev organized elements by atomic mass and chemical reactivity. Created the first widely accepted periodic table. Mendeleev Continued. Mendeleev found patterns by arranging cards with names, masses, and other physical and chemical properties of elements. for their . Rare . Earth Metals. Rare Earth Metals. There are 17 rare earth metals that make the high-tech gadgets in our lives possible. . Why Recycle . Rare Earth Metals?. We can save a lot of money by recycling the rare earth metals inside our old gadgets. Mining metals from underground is expensive, but taking apart old gadgets and reusing the metals is . Alkaline Metals. The first column of the periodic table is the group of elements known as the Group 1 or . alkali metals. . . This group includes lithium, sodium, potassium, rubidium, cesium, and francium. By definition, a metal is an element that loses one or more electrons to create a positively charged ion known as a .
