100

What does PH stand for?

Potential hydrogen 

200

Anything that occupies space and has weight

Matter

200

Smallest complete unit of an element 

Atom

200

Has a negative charge makes it possible for atoms to combine with other atoms to form bonds

Electron

200

Compounds of carbon,oxygen,hydrogen,nitrogen,sulfur 

Amino acids 

200

Increases concentration of hydrogen ions when placed in water

Acid


300

Deals with all matter that is now living or was alive at one time

Organic chemistry 

300

Change the characteristics without making a new substance 

Physical change

300

Chemical behavior of atoms depends on number of electrons in orbiting shell not missing electrons in outer shell neutral 

Stable Atom

300

Can easily be broken by heat or water

Hydrogen bond

300

Decreases concentration of hydrogen ions when placed in water

Alkali


400

studies all matter that is not alive has never been alive

Inorganic chemistry 

400

What is COHNS

Carbon,oxygen,hydrogen,nitrogen,sulfur 


400

No electric charge determines the weight of a atom neutral

Neutron

400

Broken and reformed by chemical service ; producing a chemical change with lasting results 

Disulfide bond

400

What is the PH of hair, skin and nails

4.4-5.5


500

3 basic forms of matter

Solid,liquid, gas

500

A change in a substance that creates a new substance with chemical characteristics different from those of the original substance 

Chemical change 

500

Missing electrons in outer shell seek other atoms to complete outer shell ; when combined they make molecules 

Unstable atom

500

What bond is the backbone of all protein molecules 

Peptide bond

500

On the PH scale, numbers greater than 7 indicate

Alkaline solution
