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

Carbon‚ Phosphorus and Nitrogen Cycles Humans have a great impact on each of the Carbon‚ Phosphorus‚ and Nitrogen cycles in the Ecosystem. The carbon cycle starts with the reservoir of the carbon dioxide in the air‚ the carbon atoms move from carbon dioxide through photosynthesis into atoms of organic molecules that form the plants body. These carbon atoms are then further metabolized and are eaten and turned into tissue that all organisms in the ecosystem use. Half of the atoms are respired

that reason‚ I have calculated my personal ecological footprint. Surprisingly‚ the results of the ecological footprint analysis were graver than I expected. According to them‚ it takes more than 4.5 global hectares to support my lifestyle. To be more precise‚ I need half of this area for energy production and about 30 % for crops. Food is the biggest area of my resource consumption‚ which is

many ways. The carbon cycle humans have impact the most. By burning fossil fuels we have increased atmospheric carbon dioxide by at least 35%. (Boorse‚ 2011). The impact that humans have had on this cycle has change many different elements of the natural environment. An example is the ozone layer is slowly being thinned out‚ which in turn is heating up the atmosphere of the earth. The thinning of the ozone layer is leading to changes with water level. The natural changes to the carbon cycle have been

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

Experiment 2: Aerobic Respiration in Beans We will evaluate respiration in beans by comparing carbon dioxide production between germinated and nongerminated beans. As shown in the balanced equation for cellular respiration‚ one of the byproducts is CO2 (carbon dioxide): C6H12O6 + 6 H2O + 6 O2 → energy + 6 CO2 + 12 H2O We will use a carbon dioxide indicator ( bromothymol blue) to show oxygen is being consumed and carbon dioxide is being released by the beans. Bromothymol blue is an indicator that turns yellow

In order to reduce my ecological footprint‚ I can use public transportation one more day per week rather than driving to the local stores and restaurants I frequent. Not only will it save me money on gas‚ but it also lead to less carbon emissions that produce and cause harm to the Earth. I can also fly less. I tend to fly to near destinations‚ like Massachusetts and the Carolinas. I think it could more fun if I took a road trip with family or friends or even take the Amtrak train. Last but not

BOTTLED WATER – A REPORT 1. INTRODUCTION: The global bottled water industry has become very profitable in the past ten years. Huge multinational companies currently make billions of dollars on water they simply extract from the ground‚ slap a label on and sell at competitive prices. Examples of these companies includes: Aquafina (Pepsi)‚ Dasani (Coke)‚ Perrier (Nestle)‚ Evian‚ and Fiji Water among hundreds of others. Many countries have become very oriented toward bottled water. According to

Carbon Emission and it’s Issues Recently‚ the amount of carbon emissions reached 40 billion tons. This is a record high‚ and is very damaging for Earth and humans alike. Carbon emission is a serious issue that can affect all of us in the near future. It is very harmful to the environment‚ but can also be delayed. Carbon emission is the total amount of carbon dioxide that are released in the air. There are natural and unnatural reasons for this. Nature‚ releases carbon dioxide‚ one of the most common
