the force that holds two atoms together; may form by the attraction of a positive ion for a negative ion or by sharing electrons
a three dimensional geometric arrangement of particles in which each positive ion is surrounded by negative ions and each negative ion is surrounded by positive ions; vary in shape due to sizes and relative numbers of the ions bonded
the electrostatic force that holds oppositely charged particles together in an ionic compound
the 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
a polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms
an ion made up of two or more atoms bonded together that acts as a single unit with a net charge
a mixture of elements that has metallic properties; most commonly forms when the elements are either similar in size or the atoms of one element are much smaller than the atoms of the other
the electrons involved in metallic bonding that are free to move easily from one atom to the next throughout the metal and are not attached to a particular ion
proposes that all metal atoms in a metallic solid contribute their valence electrons to form a sea of electrons and can explain properties of metallic solids such as malleability, conduction, and ductility
electron sea model
how many elements do ternary ionic compounds have?
more than 2 - one cation and a polyatomic ion (polyatomic ions have more than one atom)
metallic bonds are held together by the attraction of the ____ and the ____
positive nuclei; delocalized electrons
