What your notebook says is a simplified general statement, it is not universally true but it is true of most non-metals, ie that they cannot break the H-O bond in water, in particular they cannot do so to form oxides or hydroxides in the way that metals can. Basic solution turns red litmus into blue. ... Science Class 10 Chemistry (India) Metals and non metals Chemical properties of metals. 2. Sodium and potassium both are extremely reactive and react with air as well as water vigorously. Non-metals usually form oxides which are acidic in nature. The non-metal and oxygen gas (O 2) are the reactants in this type of reaction, and a non-metal oxide is the product. Compounds so formed are known as Ionic Compounds. Most of the metals do not react with water. Activity 3.9 CAUTION: The following activity needs the teacher’s assistance. Explore how alkali metals react with water using a series of demonstrations and videos in this lesson plan with activities for 14–16 year olds. None of the non-metals is known to react with acids. But there are exceptions also like phosphorus,carbon etc. Sodium and potassium do not react vigorously with water and oxygen. Let us check by performing the following Activity. e.g. Taking another example, Fluorine, the most reactive element of all, reacts with water to form hydrogen fluoride, oxygen is liberated. (Lithium also reacts with nitrogen.) 3. Anonymous. Reactions of alkali metals with water All the alkali metals react vigorously with cold water. 4. Generally non-metals do not react with water. 4. Reaction with oxygen: Non-metals react with oxygen to form acidic oxides. Non-metals react with oxygen to form non-metal oxides. The alkali metals react readily with atmospheric oxygen and water vapour. 4. Do all metals react in the same manner? 1 decade ago. 5. Source(s): alkali metals react violently water: https://shortly.im/lU1K0. It is generally the case that only weakly acidic or non-acidic metal oxides form metal hydroxides when in contact with water. The alkali metals such as sodium, potassium and lithium react with water to produce heat and flammable hydrogen gas, which can ignite or combine explosively with atmospheric oxygen. The reactions are highly exothermic and hence, the hydrogen gas evolved as byproduct catches fire. Non metals normally do not react with water. After breaking the covalent bonds in water, the oxygen reacts with the metal and hydrogen gas is... See full answer below. 6.
