The Horizontal Rows are named 'PERIODS'.
The Vertical Columns are named 'GROUPS'.
Horizontal rows are called periods. There are 7 periods in periodic table.
A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
The horizontal rows in the periodic table are known as periods. There are seven periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are located.
Horizontal rows of elements in the periodic table are called periods. Each period represents a different energy level, with elements in the same period having the same number of electron shells. Periods are arranged in numerical order from left to right on the periodic table.
A row on the periodic table is a horizontal arrangement of elements that share similar properties. These elements have the same number of electron shells. Each row represents one energy level or electron shell in an atom.
each row in the Periodic Table is called a period.
