. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds existing, and produced by man..
Some Basic Features of Carbon
Symbol C Atomic number 6 Mass number 12 Isotopes 12 6 C, 13 6 C, 14 6 C 1. Carbon is the first member of the group IVA. 2. Electronic configuration of this group shows that the members have four electrons in their valence shell. 3. Other members of thi..

Summary - Groups 13 to 18 of the Periodic table of elements constitute the p-block. An overview of these elements is presented here. In group 13, the characteristic group oxidation state of + 3 is known but the + 1 state gets progressively stabilized on going down the group. It ..
Grouping of Elements
In the long form of the periodic table, elements are grouped into four main blocks, purely on the basis of electronic configurations. Elements are grouped in blocks 's', 'p', 'd' and 'f' depending on the nature of orbital(s) into which the last electron of the atom ent..

'd' block elements are called transition elements. These elements occupy groups 3 to 12 on the periodic table. There are four series of transitional elements, '3d', '4d', '5d' and '6d' depending on the energy levels of 'd' orbitals. They ..
Types of Elements
On the basis of electronic configuration, the elements of the periodic table are classified into: (1) Noble gases, (2) Normal elements, (3) Transition elements, (4) Inner-transition elements, (5) Alkali metals and (6) Halogen..
Magnetic Elements
The strength of the earth's magnetic field is about 10 - 4 tesla or 1 gauss. To describe the magnetic field of earth at any place three quantities or elements are required. They are: Magnetic declination ( q ) Magnetic inclination ( d ) Horizontal component (B H..
