Ionic Lattice Structures Most ionic, metallic and covalent solids are crystalline lattices The ions, atoms or molecules are arranged in a regular and repeating arrangement Giant ionic lattic...
Metallic Bonding: Definition Metal atoms are tightly packed together in lattice structures When the metal atoms are in lattice structures, the electrons in their outer shells are free to mov...
Representing Dot & Cross Diagrams Dot and cross diagrams are diagrams that show the arrangement of the outer-shell electrons in an ionic or covalent compound or element The electrons are...
Dative Covalent Bonding In simple covalent bonds, the two atoms involved share electrons Some molecules have a lone pair of electrons that can be donated to form a bond with an electron-defi...
Covalent Bonding Covalent bonding occurs between two non-metals A covalent bond involves the electrostatic attraction between nuclei of two atoms and the bonding electrons of their outer shells No ...
Ionic Bonding As a general rule, metals are on the left of the periodic table and nonmetals are on the right-hand side Ionic bonding involves the transfer of electrons from a metallic elemen...
The Ideal Gas Equation Kinetic theory of gases The kinetic theory of gases states that molecules in gases are constantly moving The theory makes the following assumptions: That gas molecules...
Volumes & Concentrations of Solutions The concentration of a solution is the amount of solute dissolved in a solvent to make 1 dm3 of solution The solute is the substance that dissolves...
Reacting Masses The number of moles of a substance can be found by using the following equation: It is important to be clear about the type of particle you are referring to when deali...
