Scientific study of matter and the physical and chemical changes of matter
Chemistry
basic substance that cannot be broken down into simpler substances
Elements
What are the 3 parts of an atom
Proton, neutron, electron
Hair is made up from a protein called
Keratin
What does PH stand for?
Potential hydrogen
Anything that occupies space and has weight
Matter
Smallest complete unit of an element
Atom
Has a negative charge makes it possible for atoms to combine with other atoms to form bonds
Electron
Compounds of carbon,oxygen,hydrogen,nitrogen,sulfur
Amino acids
Increases concentration of hydrogen ions when placed in water
Acid
Deals with all matter that is now living or was alive at one time
Organic chemistry
Change the characteristics without making a new substance
Physical change
Chemical behavior of atoms depends on number of electrons in orbiting shell not missing electrons in outer shell neutral
Stable Atom
Can easily be broken by heat or water
Hydrogen bond
Decreases concentration of hydrogen ions when placed in water
Alkali
studies all matter that is not alive has never been alive
Inorganic chemistry
What is COHNS
Carbon,oxygen,hydrogen,nitrogen,sulfur
No electric charge determines the weight of a atom neutral
Neutron
Broken and reformed by chemical service ; producing a chemical change with lasting results
Disulfide bond
What is the PH of hair, skin and nails
4.4-5.5
3 basic forms of matter
Solid,liquid, gas
A change in a substance that creates a new substance with chemical characteristics different from those of the original substance
Chemical change
Missing electrons in outer shell seek other atoms to complete outer shell ; when combined they make molecules
Unstable atom
What bond is the backbone of all protein molecules
Peptide bond
On the PH scale, numbers greater than 7 indicate
Alkaline solution
