accuracy
how close to accepted value
alkali metals
1+ charge (hydrogen is not alkali)
alkaline earth metals
2+ charge
anion
negatively charged ion
atomic mass
average of all isotopes; mass of atom in amu; addition of protons and neutrons
atomic number
(Z) number of protons
avogadro’s number
6.022*10^23atoms/1mol
ball and stick model
the kind that you use in a lab with a ball and then a long stick showing a bond
binary compounds
a compound containing two elements
carbonate
CO3(2-)
j.j thomson
cathode ray tubes which emanated from the negative electrode and was repelled by the negative pole. He postulated that it was a stream of negatively charged particles (electrons). He measured the charge to mass ratio; plum pudding model - electrons are like raisins dispersed in a pudding of positive charge
cation
positively charged ions
chlorate
ClO3(-)
chemical change
can only be observed when a substance is changed into another substance. ex: flammability, corrosiveness, reactivity
chemical formula
shows the number of each element in the molecule.
chlorite
ClO2(-)
chromate
CrO4(2-)
chromatography
physical process; separates substances on the bases of differences in the ability of substances to adhere to the solid surface; ink chromatography - dyes to a paper
chromium ion
Cr3+
ClO(-)
hypochlorite
ClO2(-)
chlorite
ClO3(-)
chlorate
CO3(2-)
carbonate
compounds
made up of two or more different kind of elements
Copper ion charges
2+, 1+
covalent bonds
bonds between atoms by sharing electrons; result is called a molecule; occurs between two nonmetals
Cr2O7(2-)
dichromate
CrO4(2-)
chromate
dalton
created law of multiple proportions; dalton’s atomic theory: each element is made up of atoms, atoms of an element are identical, chemical compounds are formed when different elements combine with on another, chemical reaction involve the reorganization of elements
density
mass per unit volume; D=m/V; common unites are g/mL, g/cm^3
determinate error
systematic error; all results are skewed in one direction
dichromate
Cr2O7(2-)
distillation
physical process; uses the differences in volatility of substances to separate a homogeneous mixture into its components; heat the substance and as one component boils it rises and goes through cooling chamber which then returns it into liquid into another container.
electrolysis of water
chemical process; using electricity to decompose water into oxygen and hydrogen gas
empirical formula
when the ratio of molecules is most simplified
ending for monatomic anions
-ide
fahrenheit to celsius
F=9/5(C)+32
filtration
physical process; pour mixture through a filter which separates liquids from solids
elements
made up of a unique kind of atom
gas
spread very far apart; a lot of mobility
H3O(+)
hydronium
halogens
1- charge; form diatomic molecules
HCO3(-)
bicarbonate
heterogeneous
the mixture is not uniform throughout
