Period 2 element - Wikipedia

A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic nuer increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas, and an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents.

How to Draw Molecules and Chemical Bonds Just Like

These diagrams tell us that the F 2 molecule has a single bond, the CO 2 molecule has two double bonds, and the HCN molecule has one single bond plus one triple bond.. There are two main methods for constructing such diagrams. Part I of this document describes the smart way to do it. This involves counting the bonding and antibonding electrons, so we call it the BABE method.

Greenhouse Gas Emissions in Federal Buildings | WBDG

Global climate change, caused by the emissions of greenhouse gases (GHGs) that trap solar heat in the Earth''s atmosphere, has major impacts on both people and the environment. Nearly 40% of GHG emissions are attributed to the design, construction, and operation of buildings.

MONITORING AND MODELING OF INDOOR AIR POLLUTION - …

CONTINUOUS MONITORING. Continuous monitoring is a technique for sampling and measuring the real-time concentration of pollutants. Indoor air quality is subject to both temporal and spatial variations, and data on these variations would be needed to determine the concentrations to which occupants are exposed or to model indoor air pollution.

zero. Carbon neutrality can be achieved by planting enough trees so that CO2 emissions as a result of coustion would be offset by CO2 absorption by the plants. In the presence of water and light, trees convert CO2 into sugar and oxygen thru the process of photosynthesis. The average tree absorbs 10 kg (22 lbs) of CO2 per year. Carbon neutral
