the atoms are ionically bonded But for your level you may understand ionic bond as metal ion/ammonium ion(NH4+)/hydronium ion(H3O+) bonded with non-metal ion; and covalent bond as the bond formed beeen o or more non-metal atoms. 2011-06-23 18:38:53 补充： for the drawi...

metallic bonds 金属键，金属单质或者合金才会有。ionic bonds 离子键，阴阳离子间形成的，有阳离子和阴离子，一般是盐和碱中才有。covalent bonds 共价键，非金属元素之间的化学键，在离子化合物中、共价化合物中都有可能有。比如氢氧化钠中，钠离子与氢氧根离子是离子键，氢氧根里氢原子与氧原子是共价...

Well, in this simulation, you will learn the basics of atomic bonding in ionic and covalent compounds and how to distinguish those compounds experimentally. Using this knowledge you'll help your friend to analyze two mysterious substances he received from an alchemist. By testing various physical ...
e., electrically uniform—while those between unlike atoms are polar—i.e., oneatomis slightly negatively charged and the other is slightly positively charged. This partial ionic character of covalent bonds increases with the difference in the electronegativities of the two atoms.See alsoionic ...
The chemical bonding achieved between the respective materials can be, for example, ionic, covalent or metallic bonds, depending on the characteristic of the materials used to make the heat source, the interface material, and the heat ... P Ghosh 被引量: 20发表: 2004年 Ionic and Covalent B...
Ionic and covalent combinations of oleic acid and Jeffamine ED900, a homoditopic polyetheramine, lead to novel porogens, either "cataniomeric" or nonionic surfactants, bearing respectively ammonium/carboxylate ionic pairs and/or amidic bonds. The effect of the electrostatic interaction vs. the covalen...
In today’s experiment, you will determine some properties of ionic and covalent bonds. You will compare their melting temperatures and electrical conductivity in solutions. You will use the observed properties to make conclusions regarding some unknown compounds. Materials: Aluminum foil Ring stand Iro...
