Elements in the same group.... - Answer have most similar chemical properties
Formula for density - Answer d=m/v
A pair of isotopes - Answer has the same number of protons and neutrons, but a different
number of electrons
What is a chemical process? - Answer when the chemical composition of a substance is
changed
What is a physical process? - Answer when the physical characteristics of a substance is
changed without changing its chemical composition
amplitude - Answer the vertical distance from the midline of a eave to the top of the peak or
the bottom of the trough
Frequency - Answer (v, nu) is the number of waves that pass through a point in one second
Wavelength - Answer (upside down y, lambda) is the distance between identical points on
successive waves
,electromagnetic wave - Answer has electric and magnetic field components
double-slit experiment - Answer demonstrates that light has properties of both waves and
matter
blackbody radiation - Answer when a solid is heated and it emits electromagnetic radiation
Quantitative property - Answer measured and expressed with a number
Qualitative property - Answer do not require measurement and are usually based on
observation
Chemical property - Answer what a substance exhibits when it interacts with another
substance
Physical property - Answer can be measured or observed without changing the identity of
the substance

rules of sig figs - Answer any nonzero number is significant, zeros between nonzero numbers
are significant. zeros to the left of the first non zero number are not significant. zeros to the
right of the last nonzero digit are significant if a decimal is present
, rule of sig figs in addition and subtraction - Answer the answer should have the number of
sig figs after the decimal as the one with the least number of sig figs after the decimal in the
original numbers
rule of sig figs in multiplication and division - Answer the number of sig figs in the product or
quotient is equal to the original number that has the least number of sig figs
accuracy - Answer how close a measurement is to the true value
precision - Answer how close a series of replicate measurements are to one another
gold foil experiment - Answer alpha particles are fired at a thin sheet of gold foil and most
went right through it, but some bounced off of it, causing belief that most of an atom is empty
space.
Rutherford's experiment - Answer bombarded gold foil with alpha particles. showed atoms
were mostly empty space with small, dense positively charged nucleus.
Location of protons in atom - Answer nucleus
Location of neutrons in atom - Answer nucleus
Location of electrons in atom - Answer orbiting the nucleus
How to calculate the mass number of isotopes - Answer proton number+electron number
Avogadro's number - Answer 6.022 x 10^23
Quantum numbers - Answer describe the distribution of electron density
principal quantum number - Answer represented by n
designates the size of the orbital (1, 2, 3, 4, 5)
angular momentum quantum number - Answer represented by l
described the shape of the orbital
