uses of group 1 elements

Some Group 1 compounds . . Uses and Occurrences: How the element is (or was) used or where it is found. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution. element unique chemistry. Click to find more info about each use or occurrence. As a result, Cs (melting point = 28.5°C) is one of only three metals (the others are Ga and Hg) that are liquids at body temperature (37°C). An unusual trend in the group 1 elements is the smooth decrease in the melting and boiling points from Li to Cs. The densities of the Group 1 elements increase down the group (except for a downward fluctuation at potassium). !Mg2+ has a similar charge density to Li+, so the two elements show some similar chemistry (e.g., tendency to form useful organometallic compounds). The alkali metals are the elements that make up Group 1 of the periodic table: lithium, sodium, potassium, rubidium, cesium, and francium. Go to inorganic chemistry menu . Group 1 elements and uses: As a Element: Lithium has a lot of uses. A brief introduction to flame tests for Group 1 (and other) metal ions. Table 21.3 Selected Properties of the Group 1 Elements… Because beryllium's chemistry is so different from the other group 2 elements, the term "alkaline earth" is usually restricted to Mg, Ca, Sr, Ba, Ra. An unusual trend in the group 1 elements is the smooth decrease in the melting and boiling points from Li to Cs. . . Flame tests . It is also used to make tritium, types of batteries (shown above), These are lightweight and are not as toxic as lead and cadmium batteries. As a result, Cs (melting point = 28.5°C) is one of only three metals (the others are Ga and Hg) that are liquids at body temperature (37°C). . . . These elements are all much too active to exist in nature in their native state. This trend is shown in the figure below: The metals in this series are relatively light— lithium, sodium, and potassium are less dense than water (less than 1 g cm -3 ). They are called s-block elements because their highest energy electrons appear in the s subshell. Progressing down group 1, the atomic radius increases due to the extra shell of electrons for each element. Group 1 This is one of the infographics I’ve been making as part of a classroom display. Some properties and reactions of the nitrates, carbonates, hydrogencarbonates and hydrides of the Group 1 elements - limited to what is required by various UK A level syllabuses. The Group 1 elements in the periodic table are known as the alkali metals. The Group 1 elements other than hydrogen are called the alkali metals.The Group 1 elements are: Hydrogen; Lithium; Sodium; Potassium; Rubidium; Caesium; Francium; The Group 1 metals are all highly reactive silvery metals that are so reactive to air and moisture that they must be stored under an inert atmosphere or oil. The uses are, when you put it in water and then dry it, it becomes helium. Group 1 elements are known as Alkali Metals.
