you may think i am kidding but the horizontally aligned elements are called periods. The vertical is called groups.
A horizontal row on the periodic table of elements is called a period.
periodsThere are seven periods, or rows, on the periodic table.
On the Periodic table, horizontal rows are given the technical term "periods", while vertical columns are called "groups". Elements in the same period are similar in that they have the same number of energy levels.
This is where the name of the table comes from. A horizontal row of elements is called a period. A vertical column is a group.
Actinides and 14 elements in actinides
The vertical "rows" are called Columns, and the horizontal "rows" are called Periods

Horizontal row in a periodic table is called Period.There are seven periods in a periodic table.All elements in a row have same number of electronic shells.
Not really, I learned about this recently and I am positive that groups are vertical and periods are horizontal. One example would be the noble gases group, it is located in the 18th vertical column from the left
The horizontal rows of the periodic table are called Periods and the vertical rows are called groups.
