Document Summary
* define chemical element and list the four elements that form the bulk of body matter. List subatomic particles, and describe their relative masses, charges, and positions in the atom. * define atomic number, atomic mass, atomic weight, isotope, and radioisotope. Make up 96% of body weight, and 20 others present in the body, some in trace amounts (pg 26 diagram) Atoms: (greek: indivisible) more or less identical particles or building blocks that come together to form elements: every element"s atom"s differ from those of all other elements and give the element its unique physical and chemical properties. Physical properties: properties that can be detected with our senses or can be measured. Chemical properties: pertain to the way atoms interact with other atoms (bonding behavior) and account for the facts that iron rusts, animals can digest their food, and so on: atomic symbol:
