Columns on the Periodic Table are also known as 'groups'. Most notably, the electron configuration of the valance (outermost) shell will be the same for each element in a group.

What is each vertical column in the periodic table?
Each vertical column in the periodic table is group.There are 18 groups in periodic table.Seventeenth group belongs to halogens.
What each vertical column in the periodic table knows as?
Each vertical column on the periodic table are called groups, they are also known as families because they have similar chemical properties to each other.
Does the number of each period in the modern periodic table represents the number of?
The number of each period in the modern periodic table represents the number of shells. There are 7 periods in periodic table.
What does each column have in common on the periodic table?
The columns or "groups" on the periodic table have similar chemical properties, because they have the same valence : the same number of electrons, in the same type of orbital, in their outer shells.
Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
Every atom in Column 2 of a wide form periodic table has two valence electrons.
What do the numbers at the top of each column stand for in the Periodic Table?
the number of protons
What is each column in the periodic table know as?
Each column is a group of chemical elements.
What is each vertical column in the periodic table?
Each vertical column in the periodic table is group.There are 18 groups in periodic table.Seventeenth group belongs to halogens.
What is each column on the periodic table called and how many of them are there?
Each column on the periodic table is called group.There are 18 groups in total.For example 17th group belongs to Halogens.
What each vertical column in the periodic table knows as?
Each vertical column on the periodic table are called groups, they are also known as families because they have similar chemical properties to each other.
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).
Today What are the periodic table of elements recognized for?
The elements are arranged in order according to the atomic number. The periodic table is arranged so that the elements in each column have similar chemical properties.
Why the atomic radius increase in column of periodic table?
As you go down the columns of the periodic table the number of protons (and electrons) in the element increase. As the atomic number increases, so does the radius at each electron shell.
Does the number of each period in the modern periodic table represents the number of?
The number of each period in the modern periodic table represents the number of shells. There are 7 periods in periodic table.
Each column in the periodic table is called what?
A group, there ae 18 of them.
Where are groups or families on the periodic table?
They are the vertical columns on the Periodic Table. Each column (top to bottom) is considered to be a group or family.
What does each column have in common on the periodic table?
The columns or "groups" on the periodic table have similar chemical properties, because they have the same valence : the same number of electrons, in the same type of orbital, in their outer shells.
