Periods.
periodsThere are seven periods, or rows, on the periodic table.
groups go vertically and periods are the horizontal rows
The horizontal rows are called periods, there are 7. The vertical rows are groups and there are 18.
The seven horizontal rows of the table are called periods. Elements in the same row have the same number of electron shells, which determines their chemical properties.
The seven horizontal rows of the periodic table are called "periods". They are numbered from 1 to 7, with each period representing the energy level or shell in which the elements in that row have their outermost electrons. As you move from left to right across a period, the number of protons in an element's nucleus increases, resulting in a gradual change in properties.
Horizontal row in a periodic table is called Period.There are seven periods in a periodic table.All elements in a row have same number of electronic shells.

periodsThere are seven periods, or rows, on the periodic table.
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.
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.
groups go vertically and periods are the horizontal rows
The horizontal rows are called periods, there are 7. The vertical rows are groups and there are 18.
Typically, there are ten horizontal rows on a standard keyboard. This includes the top row (numbers and special characters), the second row (QWERTYUIOP), the third row (ASDFGHJKL), and the bottom row (ZXCVBNM).

18 columnsThere are 18 columns in the s, d, and p blocks on the periodic table.The f block adds 14 more to periods 6 & 7 when included.
The name comes from the "periodic" (regularly arranged) traits of the material elements. The name given to the table's horizontal rows is periods.The Periodic Table is a tabular arrangement of the elements in increasing order oftheir atomic numbers, so that elements with similar properties are in the same column. There are 18 columns, called groups, and seven rows, which are called periods, in the modern periodic table.
