because the chemical symbols are different
It is true that periodic table is divided into rows and columns. The rows are called periods and columns are called groups.
The modern periodic table is arranged in the increasing order of their atomic number and repeating properties.
There are 18 groups that make up The Periodic Table of Elements.
There are 18 periods in the periodic table. The periods are divided according to the chemical properties of elements. Elements in a group have similar properties.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
A group in Periodic Table is the column of element in periodic table
It is called the Periodic Table of Elements.
the elements in the periodic table are arranged according to the increasing atomic number and hence the elements are divided into 18 groups hence it would be easy to identify the elements
who introduced the first Periodic Table
There are no compounds on the periodic table. The periodic table only lists elements.
No, the symbol "H" stands for Hydrogen on the periodic table. The symbol "He" stands for Helium on the periodic table.
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
