(ionic bond 离子键) The attraction of oppositely charged ions is what makes ionic bonds. 2. The second way for an atom to obtain an octet of electrons is by sharing electrons with another atom. (covalent bond 共价键) 3.2: Ions 1. Define the two types of ions. 2. Use Lewis diagrams ...

65 Words 1 Page Open Document There are many properties that distinguish an ionic compound from a covalent compound. The electrical conductivity of the compound when it is dissolved in water can assist in classifying the compound as ionic or molecular. If the compound possesses the qualification of...

The general form of Lewis acid-base reactions involves the formation of a covalent bond between a species that supplies an electron pair, which is called a Lewis base, and a species that can accept an electron pair, which is called a Lewis acid. In complexes of the formula [M(H2O)6]n...

[1], they are recognized as a third group of solvents, following water and organic solvents. In spite of this, they are considerably affected by Lewis acidity or basicity of their cations or anions (Coulombic interactions), by the directionality of interactions between cations and anions, and ...
