A PERIOD.
NB A columns down the table is a GROUP.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
On the periodic table the elements are called groups.
The elements arranged according to their atomic number in the table are called periodic table.
A row on the periodic table is called a period.
It is called the Periodic Table of Elements.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.

the periodic table.
The elements arranged according to their atomic number in the table are called periodic table.
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
i don't know the scientist but it is the periodic table of the elements
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
A row on the periodic table is called a period.
Elements
The pattern of repeating properties of elements in the periodic table is called periodicity. This periodicity arises from the similar electronic structure and arrangements of elements within the table.
