What are the vertical rows called on a periodic table?
The “vertical rows” (of the periodic table) are called “columns” — or “families”. Some of the “families” have names — like “alkali metals” and “alkaline earths” for the first and second columns — well except in the first column H is not counted as an alkali metal, because H is not metallic (under any near ordinary conditions).

What are the names of the rows in the periodic table?
Key Takeaways: Parts of the Periodic Table The periodic table orders elements by increasing atomic number, which is the number of protons in the atom of an element. The rows of the periodic table are called periods. ... The columns of the periodic table are called groups. ... The three broad categories of elements are metals, nonmetals, and metalloids. ...
What happens along each row of the periodic table?
The word “periodic” means that within each row, or period, the elements show a pattern of characteristics. This is because the elements are listed in part by their electron configuration. Blocking in the periodic table: The periodic table can be broken into blocks, corresponding to the highest energy electrons.
What are the horizontal rows of the periodic table called?
The horizontal rows on the periodic table are called periods, where each period number indicates the number of orbitals for the elements in that row, according to Los Alamos National Laboratory (opens in new tab).
What are the vertical rows on the periodic table?
The periodic table is composed of vertical columns called groups and horizontal rows called periods. The periodic table is divided into groups (vertical columns) and periods (horizontal rows). Elements are placed in the periodic table in order of increasing atomic number (Z). Groups (or families) are vertical columns.
