Arrays Ion
Need your help with this Chemistry question!?
A solid metal is often known as having 'an array of positive ions in a sea "of electrons below. Write the electronic structure of magnesium atoms and use them to explain what this sentence means. Actually I do not know how to explain it. So I want you to explain in your own words, so I can get some ideas. I ask you to send it to me as soon as possible. This is really urgent.! I beg you that it should be in plain language Thanks a lot! I would greatly appreciate
This is the simplest language I can say: As long as there are chemical reactions that damage the bond between atoms or ions in the reactants, and created new bonds between atoms or ions to form product. It requires energy to break bonds and energy released when new bonds are formed. If more energy is given out of a need to put in then this will released as heat, and said exothermic reaction. If more energy is needed to break the bonds of reactants than is given at the time the product is formed and then the extra heat needed added, and said endothermic reaction. The bonds are present between atoms in the molecule caused by intramolecular forces of attraction. The forces of attraction tend to be strong. When a substance changes state from solid to liquid or from liquid to gas, then the bond is also broken. However, in this case no new chemicals are formed, so that these changes are changes physical. Bonds that are broken in a physical change is the strength of attraction between particles of compounds that hold together in solid or liquid state. This is known as the intermolecular forces of attraction. For this reason a few ice cubes is far more effective than the same mass in drinking cold water cooling, because heat is absorbed in breaking down the structure of ice. When the state changes in another direction, and intermolecular forces of attraction are formed, heat is given. So when water vapor condenses liquid at 100 ° C Heat evolved, even though the temperature remains constant. This explains why steam at 100 ° C will cause a burn injury is worse than the water at 100 ° C. In this chapter we will first discuss the different ways in which the atoms or ions can bond together in the compound. Then we will discuss how the properties of molecules or ions formed determine the type of intermolecular forces of attraction between them, and therefore the melting and boiling points and other physical properties.
