Reaction with Water. Those metals which are more reactive than hydrogen and so are placed above it in the reactivity series will react with water to form metal oxide and hydrogen gas. Top Answer. I'm not really sure what you are saying, but not all non-metals are insoluble in water. Why non-metal do not react with water or steam to evolve hydrogen gas? The non-metals cannot reduce hydrogen by donating electrons.Thus non metals do not react with water. Hence, non-metals in general do not react with acids. Generally, the non-metals do not react with acids. For example, one of the highly reactive non-metals is phosphorus and it catches fire when exposed to air that is why it is stored in water to prevent its contact with atmospheric oxygen. This is because when a substance reacts with acids, it provides electrons to the H+ ions produced by the acids. soon. Alkali metals tend to lose one electron and form ions with a single positive charge. Non-metals do not react with water. Action of water: In general, nonmetals do not react with water. Materials Metals and Non-Metals. Metals such as lead, copper, silver and gold do not react with water at all. Non-metals are themselves acceptors of electrons so there is no way they can donate electrons to the hydrogen ion of the acid. Generally, the non-metals do not react with acids.

(c)Name two metals which cannot displace hydrogen from dilute acids. ^_^ Generally, the non-metals do not react with acids. The non-metals cannot reduce hydrogen by donating electrons.Thus non metals do not react with water. Non-metals are themselves acceptors of electrons so there is no way they can donate electrons to the hydrogen ion of the acid. What type of oxides are formed when non-metals react with oxygen? 3. (AI 2008) Answer: (a) The oxides which are acidic as well as basic in nature are called amphoteric oxides. Non-metal does not react with water but it is usually very reactive in air, which is why some of them are stored in water. Some metals like Cu, Ag, Au, etc., do not liberate hydrogen gas. Such non-metals are stored in water to prevent their reaction with air. One example is chlorine gas (chlorine oxide) reacts with clouds (water) to form acids which come down as acid rain. The way, metals like sodium, magnesium and iron react with air and water is an indication of their relative positions in the ‘reactivity series’. However, all metals will not react with water. Make a distinction between metals and non-metals with respect to the nature of their oxide. Metals like sodium and potassium are highly reactive. Magnesium reacts slowly in water but reacts vigorously with steam. Question 13. Answers of why non metals don't react with acid(generally) and water are solved by group of students and teacher of Class 10, which is also the largest student You can study other questions, MCQs, videos and tests for Class 10 on EduRev and even discuss your questions like Gold, silver and platinum do not react with water. You may choose to omit these, but they do highlight an important point, namely that not all non-metals form non-metal dioxides when they react with oxygen. Answer: Ans. Reaction with acids Metals react with acids to produce respective salts along with evolution of hydrogen gas. I need detailed answers but not simple short answers. The reactivity of the metal determines which reactions the metal participates in. Non-metals do not displace hydrogen because they form negative ions by accepting electrons while hydrogen like metals forms a positive ion. When water touches alkali metals the reaction produces hydrogen gas and a strong alkaline solution, also known as a base. Why? Aluminium, however, will react with steam forming aluminium oxide and hydrogen gas. Hence, non-metals in general do not react with acids. Non-metals do not react with water. Do you mean 'why do metals and nonmetals react together?' Phosphorus is a very reactive non-metal element.If phosphorus is kept open in air,it react with the oxygen of air and catches fire.So,in order to protect phosphorus from atmospheric air,it is stored in a bottle containing water.
