Pros â It is considered easy to handle, store and transport. It is easier to extract from the ground than coal and more cost effective to transport. Cons-The burning of oil for energy production purposes, like coal, results in the emission of carbon gases into the atmosphere.In addition there are numerous safety hazards involved in the exploration of oil in onshore and offshore sites.his poses problems as non renewable sources of energy production are not only exhaustible but also have various negative effects on the environment and climate, both of which have long term effects on the earthâs system.
The element calcium (atomic number 20) has the electron configuration. 1s2 2s2 2p6 3s2 3p6 4s2. or in noble gas form : [Ar] 4s2. The element calcium (atomic number 20) has the electron configuration <br /> 1s2 2s2 2p6 3s2 3p6 4s2<br /><br /> or in noble gas form : [Ar] 4s2.
How to Write the Electron Configuration for Neon. Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital. Therefore the Ne electron configuration will be 1s22s22p6.
