metals combine with nonmetals

a) With hydrogen - Hydrogen burns in oxygen to form water vapor. A jet of hydrogen is burnt in oxygen, in an inverted funnel, as shown in figure (Fig.13.10). The product obtained, is sucked out through a test tube, kept immersed in cold water. The vapor condenses in the test tube to form wate..

Some acids can be prepared by the direct combination of a non-metal with hydrogen. For e.g., In the above reactions, the obtained gases like hydrogen chloride, hydrogen iodide and hydrogen sulphide are also called the acid anhydrides. They exhibit acidic properties, only ..

One can easily differentiate between metals and non-metals based on their placement on the Periodic Table of the Elements. The metals are elements (with the exception of hydrogen) that are found to the left of a group of elements referred to as the metalloids. Th..

Occurrence of Metals - Metals occur in nature in the free as well as in the combined states. The most unreactive metals i.e. which are not affected by air and water, like silver, gold and platinum are generally found in the free state. Most metals h..

Once the ore is calcined or roasted, the process of reduction obtains the metal. The extraction of metal from the calcined or roasted ore consists of two steps viz., Removal of the Earthly impurities. Reduction of the ore to the metal. The Earthly impurities are removed by ..

fig 1.22 - Overlapping of s and p bands in group II elements Metals are extreme examples of delocalized electrons. In a metallic crystal the electrons are free to move throughout the crystal. However, the metal ions are fixed in position and can only vibrate. When a ..
