They have different numbers of valence electrons.
As you move across the periodic table from left to right, the elements within a given row have their electrons in the same energy level (given by the number of the row they are in). They way they differ is by the number of electrons. Moving from left to right, the number of electrons increase.
All are different. Each element has its own row and column that it fits into.

Periods on the periodic table refer to the horizontal rows that categorize elements based on the number of electron shells they have. There are a total of 7 periods on the periodic table, each representing a different energy level for the elements within that row.
There are currently 118 elements currently, with 20 man-made and 88 (not 92) naturally-occurring elements. *Since 23rd October 2008.
A row of elements is known as a Period, while a column is known as a group, or family.
In the Periodic Table of Elements there are: 118 Observed Elements 114 Officially Discovered Elements 112 Officially named Elements 92 Naturally Occuring Elements 83 Non-radioactive elements
A period is a row of elements
