The density of metals is usually high. Metals such as magnesium (Mg) react with oxygen forming metal oxides, which are known as Basic oxides. Reactivity with water differs from metal to metal. They are very good conductors of electricity and heat. More reactive metal displaces the less reactive metal from its oxides, chlorides or sulphides. For example: Metals like sodium (Na) react vigorously with water at room temperature. Group 1 Elements: The Alkali MetalsThe elements in Group 1 are: These elements are known as alkali metals. Chemical Properties of Metals . Metals form an alloy with other metals or non – metals. Tungsten has a steel-like appearance but has a high melting point, low vapor pressure, and a low evaporation rate. 2Na + 2H 2 O 2NaOH + H 2. Often it is found that metals in the raw form have poor chemical composition. 6. Activity series of metals. Chemical properties of nonmetals Non-metals are also called electronegative elements because the non-metal atom form negatively charged ion by accepting electrons. You may need to download version 2.0 now from the Chrome Web Store. Fe + H2SO4 → FeSO4 + H2. Metals like copper, silver, and gold do not react with water under any conditions. The have lustreand a metallic appearance. They form through chemical interactions, which depend upon component parts and specific production methods. Metals are good conductors of heat and electricity. Out of the chemical elements present in the earth’s atmosphere, almost all chemical elements are metals. Except for Mercury. Their outer shell has 1, 2 or 3 electrons. The molecules of metals in vapour state generally have one atom. There are generally 1, 2 or 3 electrons in the outermost shell of metals. Mercury is in a liquid state. The elements are classified as metals and non-metals based on several chemical and physical properties. Metals that are more reactive will readily with less reactive metals. Mg + H2O → MgO + H2, Iron is less reactive than sodium, potassium, calcium, zinc and magnesium. The Physical Properties of Tungsten Tungsten (W) is a rare silver-white metal and belongs to group VIB of the periodic table. Some metals like sodium and potassium react vigorously with oxygen. A large amount of heat is evolved in this reaction, which results in hydrogen catching fire. A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Therefore, they lose or donate valence electrons to form positively charge ions (cations). Na → Na+ + e–. Sodium and potassium also have low melting points. A metalloid is a chemical element with properties that are in between metals and nonmetals. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. • The chemical properties of metals and nonmetals class 10 are as follows. Zn + CuSO4 → ZnSO4 + Cu. Amphoteric oxides mean that they are acidic as well as basic in nature.
