Atom-Element-Mixture
Question | Answer |
---|---|
atom | smallest particle- "indivisible" |
proton | positively charged particle with 1 amu in nucleus |
neutron | no-charge particle with 1 amu in nucleus |
electron | negatively charged particle with small mass found in energy levels around nucleus |
atomic number | the number of protons in an atom |
atomic mass | the total mass of an atom (protons and neutrons) |
element | a pure substance that cannot be separated into a simpler substanct |
mixture | 2 or more substance physically combined-- no chemical bond was formed |
compound | 2 or more substance combined to form a new substance -- chemically bonded |
heterogenous | a mixture that looks "different" |
homogenous | a mixture that looks "the same" |
solution | homogenous mixture where the particles are uniform |
colloid | a homogenous mixture where the particles are uniform, but, larger (blood, milk, mayo) |
suspension | a heterogenous mixture where you can see the particles through-out the mixture |
