Atomic bonding • The goal of bonding is to produce a full & stable outer electron shell. – 1st shell (closest to nucleus) – 2 electrons to be full – 2nd shell – 8 electrons to be full – 3rd shell – 8 electrons to be full Bonding properties • Effect of electrons – chemical behavior of an atom depends on its electron arrangement • the number of electrons in its outermost shell‚ the valence shell How does this atom behave? 2 9/22/2011 Bonding properties • Effect of

questionnaires to self-selected respondents while providing assistance and clarifications if needed‚ especially in schools and then collecting them. The strengths of Shell in my perspective are their extreme focus on the quality of their products and the fact that Shell’s lubricants are semi manufactured and mixed locally‚ which gives Shell Oman a competitive advantage when it comes to high volume accessibility. When it comes to weaknesses‚ I find that employees’ lack of adaptability with certain new

VSEPR theory says that the electron pairs in a molecule will arrange themselves around the central atom of a molecule so that the repulsion between them is as small as possible. In other words‚ the electron pairs arrange

Imperialism of the ‘Enlightened’ Nation The bombing of Hiroshima and Nagasaki ended imperialistic goals of Japan and plunged the nation into a time period of instability and need for recovery. This left Japan’s land virtually destroyed‚ its economy handicapped and its people either mentally scarred or dead in result of its attempt to expand and control the four corners of the world. Many would say that this is one of multiple reasons as to why imperialism had an overall negative effect

poem begins‚ Greenhouse’s use of word choice aids the reader to start to infer what the overall content of the poem may be about. Additionally‚ Greenhouse’s use of personification within the poem turns a seemingly irrelevant and meaningless empty shell into an individual who the reader can relate to. Therefore‚ this enables the poem to resonate and connect with the human reader even though the poem is taking place from the perspective of an inanimate object. Personification‚ ultimately allows Greenhouse

metals contain a single electron in their outer shell rendering them highly reactive. This allows them to be ready to donate this single electron to form molecules with substances like water. Halogens are also extremely reactive containing seven electrons in their outer shell. Similar to alkali metals‚ halogens need only one electron in their outer shell to become stable. The reactivity of an element increases the when the number of outer shell electrons is closer to one or seven. Elements that

Sodium Chloride came about because Sodium‚ a positively charged ion‚ has one electron in its outermost shell and Chlorine‚ a negatively charged ion‚ has seven electrons in its outmost shell. Sodium transfers the one electron to the Chlorine because in order for Sodium to have a full shell it would have needed seven more electrons to complete its shell. So instead in bonding with the Chlorine‚ its shell was completed and the ions were “happy”. 6. Johnny can’t find water on the periodic table because
