QuestionAnswer
the atom is the basic unit from which matter is constructed; a "thought experiment"; early 1800s dalton's atomic theory
the atom is the basic unit of elemental matter which exhibits the properties of the element, but the atom is make from subatomic particles today's atomic theory
the compact core of an atom nucleus
a substance that contains only one type of atom element
protons + neutrons = ? mass number
# of protons = ? atomic number
atoms of an element with different numbers of neutrons isotopes
a list of elements arranged by atomic number the periodic table
a weighted average of the atomic mass for all the naturally occurring isotopes of an elmeent atomic weight
number of protons + number of neutrons = ? atomic mass
the leements on the periodic table are divided into three categories.... name them metals, nonmetals, metalloids
elements in the same vertical column of the periodic table belong to the same group group
