The vertical columns are called groups; at one time it was common to use Roman numerals to describe the groups of elements, but now the preferred usage is standard numbers.
The groups also have names, in some cases for individual groups and in other cases for a block of groups.
Group 1 is called the Alkali Metals, the most active metals
Group 2 is called the Alkaline Earth Metals
Groups 3-12 are called the Transition Metals, and include some of our most useful metallic elements.
Groups 13-16 are the PMN Elements (Post-Transition Metals, Metalloids and Non-metals - metals are near the bottom, non-metals are near the top - a complex block)
Group 17 is the Halogens, the most active non-metals
Group 18 is the Noble Gases, the least active non-metals
The two rows of elements usually displayed at the very bottom of a Periodic Table are called the Lanthanides and Actinides, and they fit into the periodic table between Group2 and Group 3. So we might call the Lanthanides and Actinides Group 2.5
The vertical columns in the periodic table are called groups or families. They share similar chemical properties due to having the same number of electrons in their outermost energy level.

How are the elements arranged?
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.
The illustrated arrangement of the elements and their atomic properties is summarized in the?
Periodic Table
The second period at the bottom of the table is called the?
The second period at the bottom of the table is called the lanthanide series or the lanthanoid series. It consists of 14 elements with atomic numbers 57 to 70 and is located below the main body of the periodic table.
Elements on the left side of the periodic table?
Elements on the left side of the Periodic Table are "Alkali Metals". There is also one non-metal element. H(hydrogen)
What is the probable sequence in which the following clades of animals originated from earliest to most recent?
mendeleev creates a periodic table mendeleev predicts undiscovered elements moseley arranges the periodic table by atomic number a periodic table is created by mendeleev mendeleev predicts undiscovered elements the periodic table is arranged by atomic number by a man named moseley
What are the verical colums on the periodic table called?
Vertical columns are referred as groups. They are also called families.
How many colums are on the periodic table?
no fixed limit
What are colums in a periodic table?
the vertical columns are known as groups
What are the verticle columns on the periodic table?
A Group/ Family ;)
What are columns called in a periodic table and what do they have in common?
colums are called "families" or "groups". They are all placed in order according to the atomic number, and valend electrons
What elements belong to the s-block of the periodic table?
Elements in group no.(verticle) 1&2
How many grops are there in the periodic table?
There are 18 groups in the periodic table, which are columns containing elements with similar chemical properties. Each group is assigned a number and sometimes a name based on its characteristics.
What elements from this section of the periodic table all belong to the same?
Elements with the same number of valence electrons are in the same group (or vertical column).
Why is the periodic table such an important tool?
It arranges all known elements in a chart of rows and colums of increasing atomic number.
A verticle column in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
What is the name of the table of elements?
The table of elements is called the Periodic Table of Elements. It organizes all known chemical elements based on their atomic number and chemical properties.
What is a chart that lists all the known elements?
It is called the Periodic Table of Elements.
