Vocab 1
Negatively charged, subatomic particles that can either be bound to an atom or free (not found). Exists in the electron cloud surrounding the nucleus.
Electron
Water that is available for daily usage (not salty).
Freshwater
Prevention of wasteful use of a resource.
Conservation
A subatomic particle with a positive charge. Exists in the nucleus of an atom.
Proton
Basic building block of chemistry. Smallest unit into which matter can be divided into without release of electrically charged particles.
Atom
The study of matter, its properties, and the changes it undergoes.
Chemistry
Water containing small amounts of acid dissolved within it.
Acidified Water
A table in which the chemical elements are arranged in order increasing atomic number.
Periodic Table of Elements
A small number to the right and bottom of an element's chemical symbol. It also describes how many atoms of that element are in a compound.
A subatomic particle that does NOT have a charge. Exists in the nucleus of an atom.
Neutron
More than 100 substances that cannot be chemically broken down into simpler substances and are primary constituents of each other.
Element
A positively charged region at the center of an atom.
Nucleus
The state at which water is at and the physical, chemical, and biological characteristics.
Water Quality
Factors that do not change during an experiment.
Constants
What changes as a result of the independent variable manipulation in experiments.
Erosion or disintegration of rocks and materials caused by chemicals reacting with weather rather than by mechanical means.
Chemical Weathering
A variable that is not changed by the other variables being measured.
Process where a solute in a gaseous, liquid, or solid phase dissolves in a solvent to form a solution.
Dissolve
An investigation where one variable (independent variable) is changed and all other form a solution.
Fair Test
The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.
Surface Tension
Capable of dissolving more substances than any other liquid.
Solvent
The universal solvent is water.
A substance that can be dissolved into a solution by a solvent.
Solute
The quantity of matter contained in an atom of an element.
Atomic Mass
The number of protons in a nucleus always equals the number of electrons in orbit (in the electron cloud) about that nucleus.
Atomic Number
Substances that participate in a chemical equation.
Reactant
