The Bohr’s Atomic Model | Argumentative Essay | shhss | In 1913‚ a Danish physicist named Niels Bohr put Rutherford’s findings together with the observed spectra to come up with a new model of the atom in a real leap of intuition. I believe that the Bohr’s model of atom explains well about the atomic theory‚ because in his experiments it is shown and explained the structure of an atom. His famous suggestion is about that the electrons orbit around the nucleus of an atom. Bohr experimented

Salt of the Earth Flannery O ’Connor ’s novels and stories are inhabited with unique and flawed characters who are the result of O’Connor ’s satiric worldly perspective. While they are sometimes humorous‚ these misfits are usually unpleasant. Critics have termed them "grotesque‚" but O ’Connor has rejected this term because it suggests that the characters are too weird to belong in the real world. Instead‚ O ’Connor insists that the South is inhabited by many such people. For every good or evil

1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

Acid: A chemical substance (typically‚ a corrosive or sour-tasting liquid) that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red. Ionic Dissociation: Dissociation in chemistry and biochemistry is a general process in which ionic compounds (complexes‚ or salts) separate or split into smaller particles‚ ions‚ or radicals‚ usually in a reversible manner. Strength of Acids: The strength of an acid refers to its ability or tendency to lose a proton. There are very few strong acids. A
