ENGINEERING CHEMISTRY –II UNIT-I Electrochemistry Principles Redox reactions Redox stands for reduction-oxidation‚ and are electrochemical processes involving electron transfer to or from a molecule or ion changing its oxidation state. This reaction can occur through the application of an external voltage or through the release of chemical energy. Oxidation and reduction Oxidation and reduction describe the change of oxidation state that takes place in the atoms‚ ions

the Outer shell. In the periodic table‚ how does the number of metallic elements compare with the number of non-metal elements? The number of metals is more than twice the number of non-metals. Explain why sodium is more reactive than lithium. Because the metals of Group 1 become more reactive as we go down the group.Explain why fluorine is more reactive than chlorine. Chlorine is a larger atom than fluorine so it gains the electrons needed to fill its outermost

temperature‚ thus as the temperature goes up‚ the object gets brighter and brighter‚ emitting more and more energy. 9. An element is a pure chemical substance consisting of one type of atom distinguished by its atomic number. Hydrogen‚ carbon‚ lithium‚ oxygen‚ and arsenic are all elements what differentiates them all from each other is that they may be part of different groups of the periodic table and more importantly‚ their atomic number. 11.
