Chapters 1, 14
as temperature goes up this is what happens to the volume
it goes up
what is a mixture
two or more substances together
the only nonmental on the left side of the periodic table
what is hydrogen?
the definition of a solution
what is a homogeneous mixture?
the splitting of an atom
what is fission?
the definition of viscosity
resistance to flow
what do models do
they represent science
the place alkali metals are located
group #2
when heat is exiting the reaction
what is exothermic?
the combinging of small atoms
what is fusion?
the steps to the scientific process
1. state a problem, 2. hypothesis, 3. experiment, 4. gather data, 5. communicate result
the way you calculate atomic mass
adding the protons and neutrons?
these are the properties of metals (all of them)
shinny, conductive, malleable and ductile
the three factors to a reactions rate
what is changing temperature, surface area, and stirring?
the type of reaction we see in hydrogen bombs
what is fusion?
the reason we need standards in measurements
what are halogens, and noble gasses?
the definition of a polar molecule
a molecule with opposite charges on opposite sides
the definition of a concentration
the three types of radioactive particles
what are alpha, beta, and gamma?
as temperature goes down things do this (except water)
get smaller?
this is the definition of an isotope
the same element with more or less neutrons
the prefix for 4
tetra
these are the smaller numbers after the element in an equation
what are subscript?
This type of reaction rarely occurs in nature
what is fission?
