|
Period/series
|
Elements are organized horizontally in rows
|
|
|
Group/family
|
Elements that are are arranged vertically in the periodic table in groups that share similar chemical properties.
|
|
|
Metals
|
A metal is a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals.
|
|
|
Non-Metals
|
The exact opposite of a metal

|
|
Alkali Metals
|
The elements of Group 1 of the periodic table are known as the alkali metals.
|
|
|

|
Main Group Elements
|
main group elements are elements in groups, (periodic columns) whose lightest members are represented by hydrogen, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and helium as arranged in the periodic table of the elements.
|
|
|
Periodic Law
|
The Periodic Law states that the physical and chemical properties of the elements are periodic functions of their atomic numbers.
|
|
|
Mendeleev
|
Mendeleev noticed that when the elements were arranged in order of increasing atomic mass, certain similarities in their chemical properties appeared at regular intervals.
|
|
|
Moseley
|
In 1911, the English scientist Henry Moseley discovered that the elements fit into patterns better when they were arranged according to atomic number, rather than atomic weight.
|
