Noble gas with one half-filled p-orbital from each F atom, resulting in a filled bonding orbital, a filled non-bonding orbital, and an empty antibonding orbital. The highest occupied molecular orbital is localized on the two terminal atoms. This represents a localization of charge which is facilitated by the high electronegativity of fluorine. The chemistries of the heavier noble gases, krypton and xenon, are well established. The chemistry of the lighter ones, argon and helium, is still at an early stage, while a neon compound is yet to be identified. The abundances of the noble gases in the universe decrease as their atomic
Sustainability at the University of British Columbia Sustainability at the University of British Columbia Climate change is now the most serious global environmental threat. Its potential impacts include global warming, sea level rise, and increased extreme weather events. Climate change is a direct consequence of elevated greenhouse gas concentrations in the atmosphere. Greenhouse gases are gases that trap heat in the atmosphere. Some examples include Carbon dioxide, Methane, and Nitrous oxide. They are emitted from fossil fuel burning. Electricity production generates the largest share of greenhouse gas emissions. Moreover, other sources include transportation, industry, and agriculture. These gases are said to make the planet warmer by “thickening
