NO because it is having same elements that are not yet been studied rightly and there positions may change if actual properties are known and seventh period is incomplete and contains ninteen elements (Z=87 to 105).....The elements after actiniun (Z=89 to 91) are called actinides
What else can I help you with?
Which way are periods on a periodic table?
Periods are horizontal.Groups are vertical.Just think group = up and downperiod= right and left
What is the periodic table made up of?
The composition of the periodic table is made up of periods and groups. The table arranges the chemical elements based off of their atomic numbers, chemical properties and electron configurations.
What is the Number of periods on the periodic table?
The periodic table has 7 periods and 18 groups. The periods are in a horizontal line and the groups are in a straight line like up to down.
What are the horizontal collum called in the periodic table?
There seems to be a typo in your question. If you meant a "horizontal row" (left to right) of the periodic table, those are called periods. If you meant a "vertical column" (up and down) of the periodic table, those are called groups.
How do you explain how the periodic table set up?
The periodic table contains 18 columns known as groups and 7 rows known as periods. The properties of the elements are found to be periodic when arranged in order of increasing atomic number.
Why is the table of elements call the periodic table?
The Periodic Table is arranged like it is for a specific reason. It is probably called the Periodic Table because it is made up of "periods" or horizontal rows.
How many elements make up the periodic table?
118 elements.

Which direction do periods go on the periodic table?
In the periodic table of the elements, a period is a horizontal row of the table. Elements in the same period have the same number of energy levels.
Is it true there are 7 groups or rows in the periodic table?
There are 18 groups that make up The Periodic Table of Elements.
How are groups on a periodic table numberd?
From right to left (1- 18) on the periodic table. Instead of up and down (1-7) periods go vertically. (rows) groups go horizontally. (columns)
What are the rows of a periodic table called?
As with any grid, the periodic table has rows running left to right, and columns running up and down. The rows are called PERIODS and the columns are called GROUPS.
What do the columns and the rows in the periodic table represent?
A column is a chemical family, and they are split up into 18 families. An example would be column 1 which is the Alkali Metals and column 18 is the Noble Gases. A column also shares chemical properties with the elements in its group. A row is split up into groups of chemicals, and are ordered by the atomic number.
