A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
Horizontal rows are called periods. There are 7 periods in periodic table.
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.
The answer is: Au
Periods in the periodic table represent the horizontal rows that classify elements based on the number of electron shells in their atomic structure. Each period corresponds to a new energy level or shell in the electron configuration of the elements.
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
Rows in the periodic table are called periods. There are seven periods in the periodic table which represent the energy levels of the elements. Each period signifies the number of electron shells an element has.
In the periodic table chemical elements are orderd in periods and groups.
Horizontal rows are called periods. There are 7 periods in periodic table.
Horizontal rows are called periods. There are 7 periods in periodic table.
each row in the Periodic Table is called a period.
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.
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.

The periodic table of elements is divided into groups and periods. The groups (columns) are elements with similar chemical properties, while the periods (rows) represent the number of electron shells in an atom. The main subcategories include metals, nonmetals, and metalloids.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
