diagrams that show the bondingbetween atoms of a molecule and the lone pairs of electrons that may exist in the molecule.[1][2][3] A Lewis structure can be drawn for any covalently bondedmolecule‚ as well as coordination compounds. The Lewis structure was named after Gilbert Newton Lewis‚ who introduced it in his 1916 article The Atom and the Molecule.[4] They are similar to electron dot diagrams in that the valence electrons in lone pairs are represented as dots‚ but they also contain lines to represent shared

For one of them‚ this motivation was a major distraction‚ but for the other it is the only thing that kept him alive. In the Sorrow of War‚ Kien is the lone survivor of his North Vietnamese brigade and this book is his memories of the war. It is the memories of the last ten years that wasted his youth and that of his countrymen and continues to affect life after the war. During the war Kien used his affection

In 1856‚ Swiss philosopher‚ poet‚ and critic Henri-Frédéric Amiel said: “Without passion man is a mere latent force and possibility‚ like the flint which awaits the shock of the iron before it can give forth its spark”. As human beings we can choose to be either like the flint and prudently wait for a spark to come along‚ think about the consequences‚ weigh out the pros and the cons only to discover when we have reached our conclusion‚ the flame has already died out. It we can ignite ourselves with

The central storyline of “Judgement at Nuremberg” was the injustice in Nazi courts. The primary Judge of focus in the film was Judge Ernest Janning. When considering his guilt or innocence‚ I am very torn. The biggest argument in this case is can “I was only following orders” be justified and supported to prove innocence. The laws of Germany as discussed in The Nuremberg: A fair trial reading‚ state that following orders is not allowed defense. With this mind‚ the defendants are completely left without

children under 15 years. Couples were more likely than lone mothers to have a child under five years in their family (47% compared with 36%). Lone fathers were the least likely to have a child aged under five years in the family (16%). Fathers tend to have an older age profile than mothers‚ and this was observed for both lone and partnered parents. Overall‚ lone and partnered mothers were distributed in a similar pattern by age‚ as were lone and partnered fathers. The peak age group was 35–44 years

repulsion. [pic](source: http://www.mikeblaber.org/oldwine/chm1045/notes/Geometry/VSEPR/Geom02.htm) Lone pairs repel more strongly than bonding pairs of electrons therefore a lone pair distorts the shape of a molecule. Nitrogen has 5 outer electrons so ammonia will have four electron pairs around the central nitrogen atom and be tetrahedral with respect to electron pairs. Ammonia‚ NH3 has a lone pair which generates more repulsion than the 3 bonding pairs of electrons. The shape of NH3 is therefore
