Atoms
The basic unit of matter
atom
A pure substance that consists entirely of one type of atom
element
suspensions
Slight attraction that develops between oppositely charged regions of nearby molecules
Van Der Waals forces
solvent
The center of the atom, which contains the protons, neutrons, genetic material in the form of DNA
Nucleus
Same number of protons different numbers neutrons
isotope
Substance formed by the chemical combination of two or more elements in definite proportions
Compound
Smallest unit of most compounds that display all the properties of that compound
molecule
A solution with a ph less than 7
acid
Negatively charged particles located in the space surrounding the nucleus
Electron
Atom that has a positive or negative charge
ION
Chemical bond formed when one or more electrons are transferred from one atom to another
ionic bond
This type of bond is a weak attraction between a hydrogen atom and another atom
hydrogen bond
Attraction between molecules of the SAME substance
Cohesion
What three subatomic particles make up atoms?
protons, neutrons and electrons
Compound that produces hydroxide ions in solution
Base
Scal used to measure concentration
Ph scale
Pure substance that consists of one type of atom
element
Force of attraction between different kinds of molecules
adhesion
Greek word atomos means
"unable to be cut"
Type of chemical bond between atoms in which the electrons are shared
Covalent
Compound that prevents sharp, sudden changes in PH
buffers
Substance that is dissolved in a solution
solute
On the pH scale with values from 0-14 which is used to measure the concentration of hydrogen ions in a solution.
What would the pH values be for the following:
Acidic Basic Neutral
DAILY DOUBLE!
Acidic- 1-7 Basic- Above7 Neutral-7
