Question 1 - Question: Compare the properties of a typical metal and a non-metal on the basis of the following. Fill in Column A, B. Properties A Metal B Non- metal Electronic configuration ? ? Nature of oxides ? ? Oxidizing or r..

Because of very high ionization energy values, all halogens are non-metallic in character. The non-metallic character decreases as we go down the group. Therefore, the last element, iodine is a solid with a metallic lustre and forms positive ions such as I + and I 3 ..

. These developments indicate a gradual change in the life style of mankind. Today metals are so vital to the modern man that it is unthinkable to live without them. They are essential for the construction of houses, transportation, communication, electricity, household articles, scientif..

Question 1 - Question: Of these, the most ductile metal is ___________. 1. Al 2. Au 3. Cu 4. Ag Answer:..

Electronic Nature of Metals and Non-metals - We are familiar with the fact that the atoms of all elements, except noble gases, have an incomplete outermost shell. Consequently, most elements are reactive and they try to achieve the stability of the noble or inert gases by electr..

Introduction - There are 109 elements known at present. 92 elements occur in nature, while the rest are man-made. All materials on the Earth are made of these naturally occurring elements. These are classified into metals, non-metals, and metalloids. The occurrence and..

The tendency of an element to accept electrons to form an anion is called its non-metallic or electronegative character. Elements that have high electron affinity (or high electronegativity) show greater electronegative or non-metallic character. For example chlorine, oxygen and..

Non-metallic oxides react with D 2 O to form corresponding deutero acid,..
