100
Subunits of elements.
What is an atom?
100
Combination of 2 or more atoms.
What is a molecule?
100
The bond formed when electrons are transferred from one atom to another.
What is an ionic bond?
100
These donate hydrogen ions.
What are acids?
100
These organic compounds are made of simple sugars.
What are carbohydrates?
200
Positively charged particles in the nucleus.
What is a proton?
200
The most abundant compound in the body.
What is water?
200
The bond formed by the sharing of electrons between atoms.
What is a covalent bond?
200
These accept hydrogen ions.
What are bases?
200
These organic compounds are fats made of glycerol and fatty acids.
What are lipids?
300
Noncharged particles in the nucleus.
What is a neutron?
300
This occurs when a solute remains evenly distributed in a solvent.
What is a solution?
300
A type of covalent bond that has equal sharing of electrons.
What is nonpolar?
300
Below 7 on the pH scale is
What is acidic?
300
These organic compounds are made of amino acids.
What are proteins?
400
Negatively charged particles in energy levels around the nucleus.
What is an electron?
400
The particles in this are separate from the material in which they are dispersed, and they settle out because they are large and heavy.
What is a suspension?
400
A type of covalent bond that has unequal sharing of electrons.
What is a polar bond?
400
Above 7 on the pH scale is
What is basic?
400
These proteins serve as catalysts in the reactions that take place within cells.
What are enzymes?
500
The number that represents the number of protons that are present in the nucleus of the atom.
What is the atomic number?
500
A mixture in which the molecules do not dissolve yet remain evenly distributed in the suspending material.
What is a colloid?
500
Ionically bonded substances, when they go into solution, separate into charged particles.
What are electrolytes?
500
7 on the pH scale is
What is neutral?
500
Forms of an element that differ in atomic weights.
What are isotopes?
