The smallest particle of an element that can exist either alone or in
combination.
What is Atom
100
A type of strong chemical bond in which two atoms share one or
more pairs of valence electrons
What is Covalent bond
100
A chemical bond resulting from the attraction between oppositely
charged ions
What is Ionic Bond
100
A liquid that is a homogeneous mixture of two or more substances
What is Solution
100
A substance (as a dye) used to show visually usually by its capacity
for color change, the condition of a solution with respect to the
presence of free acid or alkali or some other substance.
What is Chemical Indicator
200
The amount of heat energy required to raise the temperature of 1 g
of water by 1°C; also the amount of heat energy that 1 g of water
releases when it cools by 1°C. The Calorie (with a capital C), usually
used to indicate the energy content of food, is a kilocalorie.
What is Calorie
200
The smallest particle of a substance that retains all the properties of
the substance and is composed of one or more atoms
What is Element
200
Two or more atoms held together by covalent bonds
What is Molecule
200
The dissolving agent of a solution. Water is the most versatile
solvent known.
What is Solvent
200
A chemical reaction in which two molecules are bonded together
with the removal of a water molecule
What is Dehydration Synthesis
300
An attractive force that holds together the atoms, ions, or groups of
atoms in a molecule or compound
What is Chemical Bond
300
The steady-state physiological condition of the body
What is Homeostasis
300
A substance that is needed by the body to maintain life and health
What is Nutrient
300
A compound composed of adenosine and three phosphate groups
that supplies energy for many biochemical cellular processes by
undergoing enzymatic hydrolysis
What is Adenosine triphosphate (ATP)
300
A double sugar molecule made of two monosaccharides bonded
together through dehydration synthesis
What is Disaccharide
400
Chemical transformation or change; the interaction of chemical
entities.
What is Chemical Reaction
400
A type of weak chemical bond formed when the slightly positive
hydrogen atom of a polar covalent bond in one molecule is attracted
to the slightly negative atom of a polar covalent bond in another
molecule.
What is Hydrogen bond
400
A lack of electrical symmetry in a molecule. Charge differences on
opposite ends of a structure
What is Polarity
400
An organic monomer which serves as a building block of proteins
What is Amino Acid
400
Any of the ions (as of sodium, potassium, calcium, or bicarbonate)
that in a biological fluid regulate or affect most metabolic processes
(as the flow of nutrients into and waste products out of cells)
What is Electrolyte
500
A substance consisting of two or more elements in a fixed ratio
What is Compound
500
Having an affinity for water
What is Hydrophollic
500
A substance that is dissolved in a solution
