Exam Flashcards
(50 cards)
Can be decomposed by chemical means into simpler substances
Definite shape
Pure substances
Compounds
Two or more pure substances physically mixed not chemically combined
Mixture
-273.15° c or -459.67° f or 0°k
Absolute zero
Heat required to cause a unit rise in the temperature of a mass unit
Specific heat
Hard and have very high melting points
Bonded with a strong bond into one
Do not exist as independent molecules
Covalent network
Electrons using light
Hydrogen spectrum
The ability of chemically combined atoms to attract electrons to themselves
Predict weather the electron is ionic or covalent
Electronegativity
Energy required to remove an electron from an atom
Ionization energy
Pv = nrt
Ideal gas law
Positive and attracted to negative
Used with metals and nonmetals and transfer
Ionic
Sharing Bond N2 O2
Covalent
Normally bonds through metals it also has the delocalized electrons malleable ductile
Metallic
Volume and temperature
Directly proportional
Charles law
Volume and pressure
If the pressure goes up the volume goes down
P1 over V1 equals P2 over V2
Indirectly proportional example used with people in car
Boyles
keeps the heat within
Endothermic
Puts the heat without
Exothermic
Atoms will tend to react chemically so as to achieve a noble gas electron configuration either by losing or gaining electrons or by sharing electrons with other atoms
Octet rule
Unequal
Polar
Equal
Nonpolar
3.00 * 10 to the 8th m/s
Speed of light in a vacuum
Particles arranged in a regular and repeated three-dimensional pattern
Crystalline solid
Particles arrange randomly
Amorphous solid
The number of protons in a nucleus
Atomic number
Atoms of the same element that differ in their Mass numbers
Isotope
