bonding and structure Flashcards
an ion
an ion is a charged particle formed when an atom loses or gains electrons to achieve a full outer shell
an ionic bond
the attraction between oppositely charged ions in an ionic compound
a molecular ion
a charged particle containing more than 1 atom
A giant ionic lattice
a 3d structure of oppositely charged ions held together by ionic bonds
an aqueous solution
a solution in which the solvent is water. most ionic substances are soluble in water
a covalent bond
a shared pair of electrons
A molecule
two or more atoms covalently bonded together
diatomic
two atoms covalently bonded in a molecule
lone pair of electrons
a lone pair of electrons is an unbonded pair of electrons
intramolecular bonds
bonds which occurs between atoms within a molecule
intermolecular forces
inter means between so intermolecular forces are the attractive forces between the molecules
allotrope
different forms of an element in the same physical state
metallic bonding
is the attraction between the positive metal ions and the sea of delocalised electrons in a regular lattice
alloy
is a mixture of two or more elements, at least one of which is a metal, and the resulting mixture has metallic properties
malleable
means can be hammered into shape
Ductile
means can be drawn out into thin wires
