Cham final || 100% Correct Answers.
how to count sig figs correct answers - Non zeros and zeros between nonzeros count as well as
zeros before the first non zeros
- Zeros after the last nonzero digit are usually not significant unless they are after the decimal
point
adding and subtracting sig figs correct answers round answer to the least number of decimal
places
multiplying and dividing sig figs correct answers For each multiplication or division you should
round the answer so that it has the same amount of sig figs as the number with the least sig figs
Density correct answers mass/volume
Mass correct answers density x volume
Volume correct answers mass/density
number of neutrons correct answers atomic mass - atomic number
Alpha particles correct answers Positively charged particles that can be stopped by paper
Beta particles correct answers a negatively charged particle emitted from the nucleus of an atom
during radioactive decay which can be stopped by aluminum
Gamma radiation correct answers Incredibly strong penetrating power and can be stopped by
lead
average atomic mass correct answers Multiply the masses of the isotopes by the percentages they
represent and sum them up to find the weighted average
