Building Blocks
Anything that has mass and takes up space
Matter
A collection of atoms that all have the same number os protons
Elements
Chemical that results when two or more atoms join together chemically
Molecule
A molecule in which there is an unequal distribution of negatively charges electrons causing a partial positive charge at one end and a partial negative charge at the other
Polar Compound
Molecules found in living organisms that contain carbon in rings or long chains, attached to other atoms like hydrogen, oxygen, nitrogen, sulfur, or phosphorus.
Organic molecules
The basic building blocks of matter
Atoms
A table of the cheical elemnts arranged in order of atomic number
Periodic Table
A molecule that contains atoms of at least two different elements
Compound
A weak electrical attraction between a partially positive hydrogen atom and a partially negative atom of another molecule (usually oxygen and nitrogen)
Hydrogen Bond
Two different molecules that have the same chemical formula
Isomers
The clump of neutrons and protons in the center of an atom
Nucleus
One of several forms of an element, each containing the same number of protons but a different number of neutrons
Isotopes
The name for abbreviations for compounds
Chemical Formula
Any substance in which other substances are dissolved
Solvent
Carbohydrates that are made up of more than two monosccharides
Polysaccharides
The number of protons in a atom- unique to each type of atom
Atomic Number
The sum of the protons and neutrons in an atom
Atomic Mass
This is why all isotopes of an element have the same chemical properties
They have the same number of protons
A solution in which water is the solvent
Aqueous Solution
A polysaccharide consisting of many glucose molecules found in hte cell walls of plants
Cellulose
This determines the vast majority of an atoms properties.
The number of electrons (or protons) in the atom.
Isotopes that have nustable nuclei and break down or decay over time
Radioactive Isotopes
A chemical bond formed when one or more electrons are transferred from one atom to another
Ionic bond
An attractive force that holds molecules of different substances together
Adhesion
The process by which living organisms produce larger molecules from smaller ones
Biosynthesis
