deputement 2-4 1. What is trammeling? Bonding - a close personalized kinship that forms betwixt people 2. In druggistry define chemical bonding? There is a chemical bond among monster atoms or groups of atoms in case that the forces acting between them atomic occur 18 such as to lead to the formation of an coalesce with sufficient stability to make it convenient for the chemist to encounter it as an independent molecular species. 3. Give the sum and example of the ff: a. Lewis dot Structure  The construction of snow and its compound put forward be expressed using the Lewis-dot structure This system identifies how the atoms that compile a molecule of a particular(prenominal) compound be attached (bonded) to one a nonher and (to about extent) oriented in space.  An atom is indicated by its symbol with a play of dots representing the number of valency negatrons e.g Hydrogen would be H with a maven dot, Carbo n would be a C with four dots.   When two valency electrons ar paired they are represented by two adjacent dots.   Paired valency electrons are not normally available for forming bonds with other atoms.Lewis diagrams are useful for visualizing twain ionic and covalent bonds Example : Assign formal charges to apiece atom in HCN.

First drop behind the Lewis dot structure: [pic] The two non-bonding electrons are depute to nitrogen, as are threesome electrons from the triple bond. The other three electrons in the triple bond (remember there are a primitive of 6 electrons in a triple bond) are assigned to carbon. Both carbon and hy drogen receive one electron from the single ! bond. If I total these up and subtract from the number of valence electrons associated with individually atom (5 for N, 4 for C and 1 for H), I drive the formal charges: N = 5 5 = 0 C = 4 4 = 0 H = 1 1 = 0 b. Octet Rule The  octet rule is a chemical rule of thumb that states that atoms of suffering (If you want to get a full essay, order it on our website: BestEssayCheap.com
