Title: How does an ionic bond look in a chemical equation? Post by: Julieoct on Nov 17, 2012 I get the difference between an ionic bond and a covalent bond, but how do I know which is which in a molecular expression? For instance H-C indicates a covenant bond, and H=C represents a double covalent bond. What would indicate an ionic bond? These expressions are pretty self explanatory, just like H2O, but when I get into larger and more complicated molecules I can't help but get to wondering. Thanks.
Title: How does an ionic bond look in a chemical equation? Post by: _brooksd on Nov 17, 2012 The line (-) only represents a bond, you have to look at the elements and their properties in order to find out what the bond is; for example H-O is a covalent bond as both elements are non-metals but Mg-O is an ionic bond. Simply, ionic bonds form between metals and non- metals.
Title: How does an ionic bond look in a chemical equation? Post by: micooo on Nov 17, 2012 Unfortunately we don't normally show an ionic bond in an equation,.However if a question relates to show an ionic or net ionic equation then the ionic bond is clearly shown.
e.g. Silver nitate and sodium chloride. The molecular equation is AgNO3 + NaCl = AgCl + NaNO3 Ionic equation is Ag+ + NO3- + Na+ + Cl- = AgCl + Na+ + NO3- net ionic equation Ag+ + Cl- = AgCl The sodium and nitrate ions are unchanged. |
