Discussion about ionic bond and covalent bond

Image
DICUSSION ABOUT Ionic bonds and covalent bonds In the class, Fania, ayu and lita. They are discussing last week's lesson entitled "ionic bonds and covalent bonds"   Fania: friends, I still do not understand the difference between conventional bonding and ionic bonding Ayu: The difference is just a different form of bond right?   Lita: no, But the ion bond is trebentuk due to transfer or the handover of electrons between atoms attached   Ayu: bonding? What is the bond?   Lita: Bonding is an attractive force Ayu: oh so   Lita: Simply the meaning of ionic bonds is the bond between two kinds of ions (cations and anions) by Coulomb's electrostatic forces. However, for example for complex compounds [Fe (H2O) 6] 2, Fe2 central ions with H2O molecules are also largely bound by electrostatic forces between central ions with fixed negative dipole generated by the traveling molecule.   Fania: Can you explain the example? Lita: For example on table salt

Cause and Effect

    cause and Effect Cause and effect is a common way to organize information in a text. Paragraphs structured as cause and effect explain reasons why something happened or the effects of something. These paragraphs can be ordered as causes and effects or as effects and then causes. The cause and effect text structure is generally used in expository and persuasive writing modes.         To put it another way: when an author gives reasons why something happened, he or she is explaining what caused an effect (reasons are causes and the thing that happens is the effect). Also, when a writer explains the results of an action, he or she is explaining the effects of a cause (results are effects and the thing that occurs is the cause ). The cause and effect text structure is used so commonly that you have probably written a paragraph using it and not noticed. Illnesses are caused by germs not temperature.     Many times one event causes something else to happen.
