Learning Objective
State the periodic law and explain the organization of elements in the periodic table Predict the general properties of elements based on their location within the periodic table Identify metals, nonmetals, and metalloids by their properties and/or location on the periodic table
- 1
The periodic table organizes elements by increasing atomic number, and elements in the same group or family have similar chemical properties.
- 2
Metals are typically shiny and good conductors of heat and electricity, while nonmetals generally lack these properties and are located on the upper right of the periodic table.
- 3
Dmitri Mendeleev organized elements by atomic mass and predicted the existence of undiscovered elements, while Henry Moseley later reorganized the table by atomic number.
