Significant Figures Rules - correct answer -1) All nonzero digits are significant
| | | | | | | | | | |
(not true; can be broken up into subatmoic particles [protons, neutrons, &
| | | | | | | | | | | |
electrons])
|
2) Interior zeroes (zeroes between 2 non-zero digits) are significant (not true
| | | | | | | | | | |
because of isotopes)
| | |
3) Leading zeroes (zeroes to the left of the first non-zero digit) are not
| | | | | | | | | | | | |
significant
|
4) Trailing zeroes (zeroes at the end of a number) are categorized as follows:
| | | | | | | | | | | | |
-Trailing zeroes after a decimal point are always significant
| | | | | | | |
-Trailing zeroes before a decimal point (and after a non-zero number) are
| | | | | | | | | | |
|always significant |
-Trailing zeroes before an implied decimal point are ambiguous and should be
| | | | | | | | | | |
|avoided by using scientific notation
| | | |
Dalton's Atomic Theory - correct answer -1) Each element is composed of tiny,
| | | | | | | | | | | |
indestructible particles called atoms
| | | |
2) All stoms of a given element have the same mass and other properties that
| | | | | | | | | | | | | |
distinguish them from the atoms of other elements
