Density and Measurement
The kind of glassware best used for measuring.
What is a graduated cylinder?
This particle give the atom its identity.
What is the proton?
What is atomic number?
This type of bond is characterized by the sharing of electrons.
What is a covalent bond?
One of the indicators of a chemical reaction, this solid forms when two aqueous solutions are mixed.
What is a precipitate?
The amount of matter in a given amount of space.
What is density?
These "varieties" of an element account for the decimal in average atomic mass.
What are isotopes?
This scientist organized the first Periodic Table, leaving spaces for elements that had not yet been discovered.
Who was Mendeleev?
Formed between a metal and a nonmetal, compounds containing this bond have high melting points.
What is an ionic bond?
This type of reaction always produces carbon dioxide and water.
What is combustion?
The units for density.
What is g/mL or g/cm3?
Using the gold foil experiment, he proved that the atom was mostly empty space, leading to the nuclear model.
Who is Rutherford?
This halogen has the highest electronegativity of any element.
This compound's formula is written C2H6.
What is dicarbon hexahydride?
This is the product when Ca and O2 react.
What is CaO or calcium oxide?
The technique used to find the volume of an irregularly-shaped object.
These 3-D shapes are where electrons are likely to be found around an atom.
What are orbitals?
The elements of this family are shiny, react with water, and form ions with a +2 charge.
What is the alkaline earth metals?
This compound's formula is written Cr(OH)4.
What is chromium(IV) hydroxide?
This type of reaction is characterized by two reactants: one compound, and one pure element.
What is a single replacement reaction?
This value is used to determine an experiment's accuracy when the experiment contained multiple trials.
Used in finding the average atomic mass of an element, this value is a representation of what proportion of the atoms on a planet are one particular isotope.
What is the relative or percent abundance?
This element has the largest atomic radius of the group of elements whose electron configurations end in s1.
What is francium?
Characterized by the unequal sharing of electrons, the county says compounds containing this type of bond always start with hydrogen.
Usually conducted in an aqueous solution, this type of reaction is often characterized by the formation of a precipitate.
What is a double replacement reaction?
