Information on Alkali Metals – Stanford Environmental Health & Safety.Shiny and soft enough to cut with a knife, these metals start with lithium (Li) and end with francium (Fr). Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 373(2037), 20140174. Alkali metals: The alkali metals make up most of Group 1, the table's first column. The alkali metals: 200 years of surprises. Metals, Alkali, Very Active | CAMEO Chemicals | NOAA.

The electronic configuration of alkali metals is listed below. Atomic number Name and symbol of element 3 Lithium (Li) 11 Sodium (Na) 19 Potassium (K) 37 Rubidium (Rb) 55 Cesium (Cs) 87 Francium (Fr) Electronic configuration of Alkali metals The complete list of alkali metals is mentioned below. And in this way francium (Fr) is the most reactive alkali metal. The media resources below allow educators to explore the periodic table in detail with their studentsfrom its. You can see in the above image that lithium (Li) is the least reactive alkali metal and as we move further downward in the group, the reactivity of alkali metals increases. NOVAs 'Hunting the Elements' shows viewers the world of weird, extreme chemistry.

The reactivity series of alkali metals is shown in the above image. Here is a video showing the reactivity of alkali metals with water. And because of this, the alkali metals show higher reactivity. Thus alkali metals have very less ionization energy. Hence, very less energy is required to remove the electron from its orbit. Now, alkali metals have large atomic radius as well as they have only one valence electron. The alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium. Very less ionization energy: First of all, ionization energy is the minimum energy required to remove the electron from the gaseous state or ion. Hence, alkali metals are also more reactive because of their larger atomic radius. Large atomic radius: Also the alkali metals have large atomic radius as compared to other elements on the right side of alkali metals.īecause of the larger atomic radius, the force of attraction between the nucleus and valence electron is less.Īnd because of this less force of attraction, the outermost electron can be easily lost during the chemical reaction. Only one valence electron: As alkali metals have only one valence electron, they can easily lose this electron during a chemical reaction.Īnd as they lose this electron very easily, they are highly reactive. Let me explain these reasons in short, so that you can get the exact idea behind the high reactivity of alkali metals. Solid nonmetals are also very brittle.Alkali metals are highly reactive because of many reasons like metals Noble gases Halogens Actinides Alkali metals 1 1 2 3 4 5 6 7 2 3 4 5 6 7 8. A nonmetal is typically dull and a poor conductor of electricity and heat. Be sure to include a color key with a title and DESCRIPTION of each family using the information on the power point page.

Metals are also malleable (they can be beaten into thin sheets) and ductile (they can be drawn into thin wires). Assignment As you read through the power point color code your blank copy of the periodic table. ADDucation’s list of chemical elements is compiled by Joe Connor and last. Also includes key facts and history of all chemical elements. All 118 chemical elements list, as included in the periodic table of chemical elements, with chemical symbol and classification. A metal is a substance that is shiny, typically (but not always) silvery in color, and an excellent conductor of electricity and heat. 118 Chemical Elements List Chemical Element Names & Symbols.
