Acid - 🧠 ANSWER ✔✔Any of a class of compounds whose aqueous
solutions react with and dissolve certain metals to form salts and react with
bases to form salts.
Acid anhydride / Acidic oxide - 🧠 ANSWER ✔✔An acid with one or more
molecules of water removed; for example, SO₃ is the acid anhydride of
H₂SO₄, sulfuric acid. Nonmetal oxides are ______.
Activation energy - 🧠 ANSWER ✔✔The energy, in excess over the ground
state, that must be added to an atomic or molecular system to allow a
particular process to take place.
Allotrope - 🧠 ANSWER ✔✔An element or other substance that has two or
more different forms of structures that are most frequently stable in different

,temperature ranges, such as different crystalline forms of carbon as
charcoal or diamond. Ex: O₂ and O₃
Alloy - 🧠 ANSWER ✔✔Any of a large number of substances having
metallic properties and consisting of two or more elements; with few
exceptions, the components are usually metallic elements.
Ambident - 🧠 ANSWER ✔✔A reagent or substance that can have two or
more attacking sites
Amorphous - 🧠 ANSWER ✔✔Pertaining to a solid that is noncrystalline,
having neither definite form nor structure.
Amphiprotic / Amphoteric - 🧠 ANSWER ✔✔Having both acidic and basic
characteristics.
Anion - 🧠 ANSWER ✔✔An ion that is negatively charged.
Aprotic solvent - 🧠 ANSWER ✔✔A solvent that does not yield or accept a
proton.
Base - 🧠 ANSWER ✔✔Any chemical species, ionic or molecular, capable
of accepting or receiving a proton (hydrogen ion) from another substance;
the other substance acts as an acid in giving of the proton.

,Basic anhydride / Basic oxide - 🧠 ANSWER ✔✔A metallic oxide that is a
base or that forms a hydroxide when combined with water.
Beneficiation - 🧠 ANSWER ✔✔Improving the chemical or physical
properties of an ore so that the metal can be recovered at a profit. Also
known as mineral dressing.
Bond energy - 🧠 ANSWER ✔✔The heat of formulation of a molecule from
its constituent atoms. [Note: Usually tabulated as positive numbers, which
represent the energy required to dissociate (break apart) a gaseous
diatomic molecule into its constituent gaseous atoms, or a corresponding
fraction for a larger molecule composed of two elements.]
Born-Haber cycle - 🧠 ANSWER ✔✔A sequence of chemical and physical
processes by means of which the cohesive energy of an ionic crystal can
be deduced from experimental quantities; it leads from an initial state in
which a crystal is at zero pressure and 0°K to a final state that is an
infinitely dilute gas of its constituent ions, also at zero pressure and 0°K.
∆H = (atom. NRG) + (ion. NRG) + (atom. NRG) + (EA) - (U lattice NRG)

, Bridging ligand - 🧠 ANSWER ✔✔A ligand in which an atom or molecular
species that is able to exist independently is simultaneously bonded to two
or more atoms.
Catalyst - 🧠 ANSWER ✔✔Substance that alters the velocity of a chemical
reaction and may be recovered essentially unaltered in form and amount at
the end of the reaction.
Catenation - 🧠 ANSWER ✔✔The property of an element to link itself to
form molecules, as with carbon.
Chalcogen - 🧠 ANSWER ✔✔One of the elements that form Group 16/VIA
of the periodic table; included are oxygen, sulfur, selenium, tellurium, and
polonium.
Close packed - 🧠 ANSWER ✔✔Referring to a crystal structure in which the
lattice points are centers of spheres of equal radius arranged so that the
volume of the interstices between the spheres is minimal.
Conductor - 🧠 ANSWER ✔✔A wire, cable, or other body or medium that is
suitable for carrying electric current.
