Bonding Flashcards
Ionic Bonding
the transfer of electrons from a positively charged metal to a negatively charged non-metal.
Ionic Compounds Properties
strong bonds make them hard and brittle, high melting and boiling points, form crystals, soluble, insulators in solid state but conductors in molten state.
Metallic Bonding
when metals bond the atoms adopt a lattice structure and the valence electrons become delocalized resulting in a sea of electrons.
Metallic Bonds Properties
high melting and boiling points, malleable, good conductors, insoluble, high density
Covalent Bonding
sharing of electrons between two non-metals to complete their valence shells
Covalent Substances
covalent molecular substances, covalent network substances.
Properties of Covalent Molecular Substances
low boiling and melting points, poor electrical conductivity, soft and brittle, depends on polarity
Properties of Covalent Network Substances
very high melting and boiling points, very strong, poor conductors, soluble
Naming Ionic Compounds
metal first, then the nonmetal with the suffix -ide
Naming Covalent Compounds
first element is the furthest left or lowest in the group, second element with the suffix -ide
Metallic Bond Strength
increases with the number of valence electrons, as more electrons in the sea equals greater charged cation.
3D Lattice
particles are arranged in layers that repeat in 3D. They have very high melting and boiling points, insoluble and insulators.
2D Lattice
flat, repeating arrangement of particles in 2D. Conductive, thin, hard, flexible.
