17 wrz 2024 · Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).
25 lis 2019 · The alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium. Alkali Metal Properties. The alkali metals exhibit many of the physical properties common to metals, although their densities are lower than those of other metals. Alkali metals have one electron in their outer shell, which is loosely bound.
Chemical properties of the alkali metals. Learn about and revise the alkali metals in group 1 of the periodic table with this BBC Bitesize GCSE Chemistry (Edexcel) study guide.
Scroll down to learn about the uses of alkali metals. Alkali metals or Group 1A elements belong to a common group due to its ns 1 valence electronic configuration. The properties of an element have periodic dependence on its atomic number but not on atomic weight.
27 sty 2016 · The alkali metals are the elements located in group IA of the periodic table (the first column). The key characteristic these elements share in common is that they all have one electron in the outer electron shell. This lone electron is loosely bound, making this a set of reactive metallic elements.
