The reaction of alkali metals with water is represented by the following equation: 2 M(s or l) + 2 H 2 O (l) --> 2 M(OH) 2 (aq) + H 2 (g) Where M is the alkali metal.The heat given off by this reaction immediately melts the sodium and potassium and is frequently sufficient to ignite the hydrogen gas produced: MEMORY METER. 23. This preview shows page 29 - 31 out of 32 pages. Most of the chemistry has been observed only for the first five members of the group; the chemistry of radium is not well established due to its radioactivity. Identify the element that fits each description. The alkaline earth metals react with 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 and therefore easier to remove (recall ionization energy trends!). Chem., Int. Course Hero is not sponsored or endorsed by any college or university. Reactivity of Alkaline Earth Metals. Alkaline Earth metals are very reactive because they readily give up their two valence electrons to achieve a full outer energy level, which is the most stable arrangement of electrons.

The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). The chemical reactivity of Alkaline Earth Metals increases down the group. Alkali metals are among the most reactive metals. The alkaline earth metals are less reactive and thus more difficult to initiate a reaction when compared to the alkali metals. Be is kinetically inert … All alkali metals are highly reactive towards the more electronegative elements such as oxygen and halogens. The alkaline-earth elements are highly metallic and are good conductors of electricity. Therefore not only do the desired products form very slowly, but once formed, they are also reactive enough to attack the solvent or the remaining starting materials. When alkaline earth metals are heated to high temperature with hydrogen gas, metal hydrides are given. Introduction: scope of the review.

The alkaline earth metals have the common properties of metals, are silvery-grey in colour and good conductors of heat and electricity. Barium forms barium peroxide (BaO 2 ) because the larger O 2 2− ion is better able to separate the large Ba 2 + ions in the crystal lattice. A high heat source is needed for Mg combustion. Trends in Reactivity of Group 2 Elements (alkaline-earth metals) All the group 2 elements (M (s)), except beryllium, react with water (H 2 O (l)) to form hydrogen gas (H 2(g)) and an alkaline aqueous solution (M(OH) 2(aq)) as shown in the balanced chemical equations below: Alkali metals exhibit high chemical reactivity. Reactions of Alkaline Earth Metals. In 2014, chemists described a magnesiacyclopentadiene, which they calculated to be antiaromatic.2 But the compound’s structure couldn’t be confirmed, so its antiaromaticity remained theoretical.

The elements in group 2 of the periodic table are called the alkaline earth metals. Assign to Class. All alkali metals are highly reactive towards the more electronegative elements such as oxygen and halogens. They were given that name because they were first isolated from compounds in which they were combined with oxygen. 1 For a variety of reasons, however, most of the derivatives remained poorly characterized.
