List of the First 20 Elements and their Physical Properties Atomic Radii (pm) of the First 20 Elements: - Atomic radii decreases when moving down a period‚ as the number of protons increases‚ which thence increases the effective nuclear charge. - Atomic radii increases when moving down a group‚ as the number of shells increases‚ which thence increases shielding. - The downward-sloping pattern on the above graph shows the decrease in atomic radii down a period‚ and the sudden jumps

Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

5.3.7 Effect of carbon supplements Supplementation of sugars‚ which may act either as carbon sources or inducers‚greatly affect the growth of microorganism. In case of CMCase‚out of the supplemented sugars‚glucose‚sucrose‚maltose‚lactose‚wheatbran and CMC‚ wheat bran show maximum increase in enzyme production. On addition of glucose‚ maltose‚ lactose‚wheat bran and xylan‚ the maltose resulted in an increment in xylanase production (24.96 IU/ml) by SmF. An induction in the enzyme production/activity

Market Failure and Carbon Prices Climate change has become an issue of global discussion and it is the result of market failure. The effects of the increasing volume of carbon dioxide and greenhouse gases on the global temperature have become a major environmental issue throughout the world. Carbon emissions worldwide need to be reduced in order to avoid serious climate change. To encourage companies to invest in cleaner technology and reduce carbon emissions‚ the government has to attach a cost

Where to Begin: the Chicken or the Egg? White‚ round‚ smooth are picturesque descriptions of an egg. An egg has a simple exterior that is easy to describe. However‚ this simple egg has a complex ecological footprint that contributes to the destruction of our planet‚ people‚ and prosperity. Eggs are essential to every dimension of the earth. An egg is a nutritious source protein and vitamins‚ triggering the performance of health maintenance in humans. Not only are eggs an exceptional source of

Sean Byrne Teacher Biology Honors 13 August 2014 Unit 1 Chapter 3 1) a. Monomers are small‚ simple molecules that when put together create carbon compounds‚ and polymers are molecules that consist of repeated units. b. Functional groups are made of clusters of atoms‚ while macromolecules are large polymers. c. A monosaccharide is a simple sugar‚ but a disaccharide is known as a double sugar‚ or two monosaccharaides. d. Long chains of amino acids are called polypeptides‚ and proteins are composed

group. A carbonyl group is a carbon atom doubly bonded to an oxygen atom. [pic] Both molecules have a carbonyl group‚ the difference the number of carbons bonded to the carbonyl carbon. An aldehyde will have none or one and a ketone will have two carbons. All aldehydes‚ except formaldehyde‚ will have a hydrogen atom on one side of the carbonyl carbon and at least on carbon on the other side. [pic] All ketones have a carbon on each side of the carbonyl carbon. [pic] Remember that the

INTRODUCTION Hydrocarbons are compounds that consists carbon and hydrogen only. They are the simplest organic compounds. Hydrocarbons‚ because of their number and variety‚ are classified into different ways. One way of classifying hydrocarbons is in which way carbon atoms are connected. It can be classified as either a chain aliphatic hydrocarbon or a cyclic hydrocarbon. Chain aliphatic hydrocarbons are compounds that are linked either in a single or branched chain. An example of this is hexane

isotopic dating is recognized as carbon dating. The radioactive decay of carbon-14 is used in carbon dating. Carbon-14 atoms are equally distributed over Earth ’s biosphere. These atoms are combined with carbon-12 and carbon-13. Organisms contain the same ratio of carbon-14 to carbon-12 and carbon-13 because organisms are always taking in carbon. When the plants intake carbon dioxide‚ they are using these various carbon isotopes. When a plant is eaten by an animal‚ the carbon-14 atoms are then transferred
