Share your videos with friends, family, and the world Thyristor current can be reduced to a value below the value of holding current. Since, the thyristor is turned off forcibly it is termed as a forced commutation process. The basic electronics and electrical components such as inductance and capacitance are used as commutating elements for commutation purpose.

May 08, 2014 · As very few elements could be arranged in such groups, this classification did not get wide acceptance. Law of Octaves An English Chemist Newland (1864) stated that if the elements were arranged in the ascending order of their atomic masses, every eight element will have similar properties to the first.

Multiple Choice Questions 1. Upto which element, the Law of Octaves was found to be applicable (a) Oxygen (b) Calcium (c) Cobalt (d) Potassium 2. According to Mendeleev's′ Periodic Law, the elements were arranged in the periodic table in the order of (a) increasing atomic number (b) decreasing atomic number (c) increasing atomic masses Elements that are in the same group of the periodic table have similar chemical properties because they have the same number of electrons in their outer shell. The electrons in the outermost occupied shell (or shells) determine the chemical properties of the atom; it is called the valence shell .
The elements X, Y, Z and J have the indicated electron configurations starting with the innermost shell. The most metallic element is : The most metallic element is : (1) X = 2, 8, 3

The Periodic Table • Periodic Law - When the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties • Modern Periodic consists of: Periods - Horizontal rows of the periodic table (side to side) Groups or families - – vertical (up and down) composed of the same elements. The Periodic Table of the Elements lists all the known elements. Each element's square has its atomic number, name, and one or two letter chemical symbol. For example, 1 hydrogen H 8 oxygen O Many different experimental techniques have been developed to test which elements are present in a sample.
