The simplest form of chemical matter
Element
Science that deals with the composition, structure and properties of matter and how matter changes under different conditions
chemistry
Combination of two or more substances that are united physically in any proportion
Physical mixture
Substances that have a pH below 7.0
acid
also know as redox, is a chemical reaction the oxidizing agent is reduced
oxidation reduction
Are chemical combinations of two or more atoms of different elements that are united chemically
Compound Molecules
the study of substances that contain the element carbon
organic chemistry
Colorless orderless tasteless gas is the lightest element known
Hydrogen
alkalis
rapid oxidation of a substance of a substance accompanied by light and heat
Combustion
Are particles from which all matter is composed
Atoms.
chemistry with compounds that do not contain the element carbom
inorganic chemistry
Most abundant element found on earth
Oxygen
atom that carries an electrical charge
Ion
caused by highly reactive atoms or molecules. can cause damage to DNA,eventually cause disease and death
Free radicals
solid liquid and gas
States of matter
a change in the form or physical properties of a substance without the formation of a new substance
physical change
Most abundant of all substances about 65 % of human body
Water ( H2O)
Ion with a positive elecrical charge
Cation
Used to stabilize oxidation in skin care producuts
Antioxidents
contain two or more atoms of the same element that are united chemically
Elemental molecules
change is chemical composition of a substance in which a new substance is formed having different properties from the original
chemical change
Chemical compound colorless liquid odor and taste are slightly acidic
Hydrogen peroxide
ion with a negative electrical charge
anion
acid and alkaline mixed into equal proportions to neutralize eachother
acid-alkali neutralization reactions
