Unit 2 Chem review

The force that holds two atoms together; may form by the attraction of a positive ion for a negative ion or by sharing electrons

• Ionic bond

• Chemical Bond

• Covalent bond

• Lattice energy

The electrostatic force that hold oppositely charged particles together in an ionic compound

• Ionic bond

• Lattice energy

• Electrolyte

• Combustion reaction

A compound composed of only two elements, typically a metal and a non-metal

• Covalent bond

• Endothermic reaction

• Binary Ionic Compound

• Synthesis reaction

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

• Mon atomic atom

• Lattice Crystal

• Formula unit

• Ionic attraction

The energy required to separate one mole (chunk) of the ions of an ionic compound, which directly relates to the size of the ions bonded and is also affected by the charge of the ions.

• Lattice Crystal

• Lattice Energy

• Ions

• Lattice mole

The simplest ratio of ions represented in an ionic compound

• Formula equation

• Skeleton unit

• Skeleton equation

• Formula Unit

An ion made up of two or more atoms bonded together that acts as a single unit with a net charge

• Ion

• Polyatomic Ion

• Monatomic Ion

• Dual ion reaction

A polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms

• Oxygen

• Oxyhydroxide

• Oxyacid

• Oxyanion

A mixture of elements that has metallic properties, most commonly forms when the elements are either similar in size (substitutional alloy) or the atoms of one element are much smaller than the atoms of the other (interstitial alloy)

• Alloy

• Metal

• Compound

• Bond

A chemical bond that results from the sharing of valence electrons.

• Polar bond

• Alloy

• Covalent bond

• Ionic bond
