what is a average atomic mass
the average mass of an element
a table were are arranged by atomic number
the weighted average mass of all natural occering isotope of an element measured in atomic mass units
what is the periodic table
a table were the elements are arranged by increasing atomic number and by changes in chemical and physical properties
a table were it is organized by periods and groups
what is the period
the perpendicular columns in the periodic table

what is the groups
the vertical columns in the periodic table
the horizontal rows in the periodic table
a perpendicular columns in the periodic table
what is the electronic dot diagram
uses the chemical symbol of an element surrounded by dots to represent the number of electrons on the outermost of the element.
uses dots to represent chemical compounds

metals that can be rolled or hammered into sheets
same property's as metals and nonmetals
what does it mean for a metal to be malleable
metal that's drawn into wires
same property's of both metals and nonmetals
metals that can be rolled or hammered into sheets
what is ductile
metal that is drawn into wires
charged metallic ions surronded in a electron
