Question
Answer
study of the composition and stucture of the material and the changes that materials undergo best describes the science of   chemistry  
the branch of science that includes the study of materials and process that occur in livings is   biochemistry  
the branch of chemistry that is concerned with the identification and composition of materialsis   analytical chemistry  
the study of substance containing carbon is   organic chemistry  
the branch of chemistry concerned withtheproperties, changes, and relationships betwen energy and matteris   theoretical chemistry  
basic researchis   carried out for the sake of increases knowlege  
a physical property may be investigated by   melting ice  
two features that may distinguish matter are   mass and volume  
an example of an extensive physical property is   mass  
which of the following is an intensive physical property   color  
which of the following obervations is quantitative   the liquid turns blue litmus paper red  
quantitative observation are recorded using   numerical infomation  
qualitative observation are recorded using   non-numerical infomation  
the SI standard unit for length and mass are   meter and kilometer  
the metric unit for length that is closes to the thickness of a dime is the   milimeter  
the symbol for the metric unit used to measure mass is   g  
the unit m3 measures   volume  
the symbol that represents the measure unit for volume   mL  
the SI base unit for time is the   second  
a change in the force of earth's gravity on an object will effect its   weight  
a nuclear partical that has about the same mass as a proton, but with no electricalcharge, is called   neutron  
gamma rays are   elecctromagnetic waves  
phosphorus-33 contains   18 neutrons  
a nuclear partical that has about the same mass as a proton, but with no electrical charge, is called   neutron  
the smallest unit of an element that can exsit alone or in combination with other such partcals is an   atom  
which of the following forms of radiation has the greates penetrating power   gamma rays  
as the atomic number increases, the number of electrons in an atom   increase  
what does the 101 in 256/101 Md reprsent   the atomic number  
who called an "atom" an atom   democritus  
what is the atomic number of tungsten   74  
the distance between to successive peaks on a wave is its   wavelenght  
an element with 8 electrons from its highest main energy level is a   noble gas  
the emission of electrons from metals that have absored photons is called   photoelectric effect  
the region outside the nucleus where an electron can most probably be foud is   electron cloud  
how many quantum numbers are needed to discribe the energy state of an electronin an atom   4  
the wave modle of light did not explain   the photoelectric effect  
which group are the noble gas   18  
what is the total number of electrons needed to fill the first two main energy levels?   10  
the atomic sublevel with the next highest energy after 4p is?   5s  
the number of orbitals for the d sublevel is   5  
To which group do lithium and potassium belong?   alkali metals  
The discovery of the noble gases changed Mendeleev's periodic table by adding a new   group  
Elements in a group or column in the periodic table can be expected to have similar   properties  
Mendeleev predicted that the spaces in he periodic table represented   undiscovered elements  
Mendeleev attempted to organize the elements based on their   properties  
In the modern periodic table, elements are orderd according to   increasing atomic number  
The most useful source of general information about the elements for anyone associated with chemistry is a   periodic table  
Argon, crypton, and xenon are   noble gases  
ONe-half the distance between the nuclei of identical atoms are bonded together is called the   atomic value  
To which group do flourine and chlorine belong?   Halogens  
The principle that states that the physical and chemical properties of the elemtns are periodic functions of their atomic number is   the peridoic law

covalent bond results when what is shared   electrons  
most cemical bonds are   partly ionic and partly covalent  
an octet is equal to   8  
which of the following is not an example of a molecular formula   B  
if two covalent bonded atoms are identical, the bond   non-polar covalent  
compare with ioniccompounds, molecularcompounds   have lower melting points  
the B--F in BF3 is   ionic  
the chemical bond formed when two atoms share electrons are called   covalent bonds  
atoms are what when they are combined   more stable  
a mutual elecrtical attraction between the nuclei and valence electrons of a different atoms that binds the atoms together is called   chemical bonds
