|---|---|---|---|---|---|
| Compound | a substance that is made up of two or more different elements chemically combined
🗑

| Octet Rule | when bonding occurs, atoms tend to reach an electron arrangement with 8 electrons in the outermost shell
🗑
|
||||
| ion | a charged atom or group of atoms
🗑
|
||||
| Ionic bond | the force of attraction between oppositely charged ions in a compound
🗑
|
||||
| Transition Metal | one that forms at least one ion with a partially filled d-sublevel
🗑
|
||||
| molecule | a group of atoms joined together. It is the smallest particle of an element or compound that can exist independently
🗑
|
||||
| valency | the number of atoms of hydrogen or any other monovalent element with which each atom of an element combines
🗑
|
||||
| electronegativity | the relative attraction that an atom in a molecule has for the shared pair of electrons in a covalent bond
🗑
|
||||
| Van der Waals forces | weak attractive forces between molecules resulting from the formation of temporary dipoles
🗑
|
||||
| dipole-dipole forces | forces of attraction between the negative pole of one molecule and the positive pole of another
🗑
|
||||
| hydrogen bonds | particular types of dipole-dipole attractions between molecules in which hydrogen is bonded to nitrogen, oxygen or fluorine. The hydrogen atom carries a partial positive charge and is attracted to the electronegative atom in another molecule.
🗑
|
||||
| hydrogen bonds contd. | Thus, it acts as a bridge between two electronegative atoms
🗑
