Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4 Valence electrons: 4 Property: Non-metal Abundance: Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon: The Covalent Bond

The compound pendulum Consider an extended body of mass with a hole drilled though it. Suppose that the body is suspended from a fixed peg‚ which passes through the hole‚ such that it is free to swing from side to side‚ as shown in Fig. 98. This setup is known as a compound pendulum. | Figure 98: A compound pendulum. | Let be the pivot point‚ and let be the body’s centre of mass‚ which is located a distance from the pivot. Let be the angle subtended between the downward vertical (which passes

August 15‚ 2012 COMPOUND MICROSCOPE A compound microscope is an optical instrument used to see objects that are too small for the naked eye. A compound microscope is a microscope fitted with two or more convex lenses. The high magnification produced by these lenses together enables a detailed study of micro-organisms‚ cells and tissues. These types of microscopes are therefore widely used in scientific and medical research. The basic design of a compound light microscope consists

COrdination compounds Question 9.1: Explain the bonding in coordination compounds in terms of Werner’s postulates. =Werner’s postulates explain the bonding in coordination compounds as follows: (i) A metal exhibits two types of valencies namely‚ primary and secondary valencies. Primary valencies are satisfied by negative ions while secondary valencies are satisfied by both negative and neutral ions. (In modern terminology‚ the primary valency corresponds to the oxidation number of the metal

required of L&D professionals and how L&D roles are specified. We discuss the CIPD HR Profession Map and how we can use it to assess our professional development needs. We then move on to look at how we deliver our L&D service‚ considering: who are our customers‚ how well do we meet their needs and what can we do to improve our service delivery. In the final section of the chapter we look at the concept of Continuing Professional Development (CPD) and give some practical tips on how to complete a CPD

Planimetric Map. A planimetric map presents only the horizontal positions for the features represented. It is distinguished from a topographic map by the omission of relief‚ normally represented by contour lines. Sometimes‚ it is called a line map. Topographic Map. A topographic map portrays terrain features in a measurable way‚ as well as the horizontal positions of the features represented. The vertical positions‚ or relief‚ are normally represented by contour lines on military topographic maps. On maps

“Cartographers have strongly emphasised the visible‚ the tangible‚ the static‚ the physical and the historical values over the invisible‚ intangible‚ dynamic‚ human and futurist aspects of the world.” Cartographers have long ago developed maps for understanding the complexity of our environment. Whether it started for war or general education‚ cartography has developed over time in an astonishing way. While analysing the quote ‘Cartographers have strongly emphasised the visible‚ the tangible
