halogens to give the corresponding halides: Reactivity of alkaline earth metals increases as size increases, because the valence electrons are farther away from the nucleus, It’s important to note that beryllium is significantly less reactive. Reactions of alkali metals with oxygen When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. After they have seen each experiment, you could pause the video to give them a chance to record their observations. The oxides are much less reactive than the pure metals. This produces a layer of dull oxide on the surface of the metal, called tarnish. How do the Alkali Metals React with Oxygen? + oxygen     How do they react with water, oxygen and chlorine? The elements of Group 2 are beryllium, magnesium, calcium, strontium, barium, and radioactive radium. Potassium tarnishes... very quickly. They will burn brightly, giving white solids called oxides. All alkali metals react with oxygen in the air to form... metal oxides. The rate of reaction with oxygen, or with air, depends upon whether the metals are in the solid or liquid state , as well as upon the degree of mixing of the metals with the oxygen or air. What are alkali metals? 1.6.10 assess and manage risks associated with the storage and use of alkali metals and recall that alkali metals are easily cut, are shiny when freshly cut and tarnish rapidly in air; 1.6.11 demonstrate knowledge and understanding that Group 1 (I) metals react with water to produce hydrogen and a metal hydroxide, and give observations for the reactions; Advertisement Remove all ads. 4Na(s)  +       Due to formation of film of oxides of beryllium and magnesium, they do not continuously react with oxygen.
