What are the two characteristics of carbon?
Solution : The two features of carbon that give rise to a large number of compounds are as follows: (i) Catenation: It is the ability to form bonds with other atoms of carbon. (ii) Tetravalency: With the valency of four, carbon is capable of bonding with four other atoms.
What are the characteristics of carbon that makes it special?
Carbon atoms are unique because they can bond together to form very long, durable chains that can have branches or rings of various sizes and often contain thousands of carbon atoms. Silicon and a few other elements can form similar chains; but they are generally shorter, and much less durable.
What are the physical properties of carbon?
Physical Properties of Carbon: Carbon is a unique element. It occurs in many forms. Some of the examples of the pure form of carbon are coal and soot. It is soft and dull grey or black in color.
What are the characteristics of light?
Characteristics of Light. 1 Electromagnetic spectrum. Maxwell’s equations united the study of electromagnetism and optics. Light is the relatively narrow frequency band of 2 Speed of light. 3 Polarization.
What are the properties of graphite and carbon?
Properties and uses. Graphite, on the other hand, is a soft slippery solid that is a good conductor of both heat and electricity. Carbon as diamond is the most expensive and brilliant of all the natural gemstones and the hardest of the naturally occurring abrasives. Graphite is used as a lubricant.
What are the properties of carbon allotropes?
Interestingly, carbon allotropes span a wide range of physical properties: diamond is the hardest naturally occurring substance, and graphite is one of the softest known substances. Diamond is transparent, the ultimate abrasive, and can be an electrical insulator and thermal conductor.
