|---|---|---|---|---|---|
| alloy | mixture of elements that has metallic properties most commonly forms when the elements are either similar in size or the atoms of the elements are much smaller than the atoms of the other.
🗑
|
||||
| anion | an ion that has a negative charge
🗑
|
||||
| cation | an ion that has a positive charge
🗑
|
||||
| chemical bond | the force that hold two atoms together; may form by the attraction of a positive ion to a negative ion or by sharing electrons
🗑
|
||||
| crystal lattice | 3D geometric arrangement of particles in which each positive ion is surrounded by negative ions and each negative ion is surrounded by positive ions
🗑
|
||||
| delocalized electron | electrons involved in metallic bonding that are free to move easily from one atom to the next throughout the metal ad are not attached to a particular atom
🗑
|
||||
| electrolyte | an ionic compound whose aqueous solution conducts an electric current
🗑
|
||||
| electron sea model | proposes that al metal atoms in a metallic solid contributes their valence electrons to form a "sea" of electrons and can explain properties of metallic solids such as malleability, conduction and ductility
🗑
|
||||
| formula unit | simplest ratio of ions represented in an ionic compound
🗑
|
||||
| ionic bond | electrostatic force that holds oppositely charged particles together in an ionic compound
🗑
|
||||
| ionic compound | compounds that contain ionic bonds
🗑
|
||||
| lattice energy | energy required to separate one mole of the ions of an ionic compound, which is directly related to the size of the ions bonded and is also affected by the charge of the ions
🗑
|
||||
| metallic bond | attraction of a metallic cation for delocalized electrons
🗑
|
||||
| monatomic ion | an ion formed from only one atom
🗑
|
||||
| oxidation number | positive or negative charge of a monatomic ion
🗑
|
||||
| oxyanion | polyatomic ion composed of an element, usually a nonmetal bonded to one or more oxygen atoms
🗑
|
||||
| polyatomic ion | ion made up of 2 or more atoms bonded together that act as a single unit with a net charge
🗑
