Groups! They all have same number of valence electrons in outer shell, which leads to similar chemical and physical characteristics.
periods are the rows and families are the columns
The columns are known as groups.
they are called groups or families
There are 18 columns on the periodic table.They are called groups or families.
The columns on the periodic table are called Groups.
colums are called "families" or "groups". They are all placed in order according to the atomic number, and valend electrons
All elements a given column have the same number of valence electrons.
they are called groups or families
The columns on a periodic table are called "groups" or "families." Groupings are based on the number of valence electrons elements within the same group have in common, which influences their chemical properties.
Not all, but some Groups/Vertical columns have their own name. Group (I) ; Alkali Metals. Group(II) ; Alkaline Earth Metals. Group(VII) ; The Halogens Group (VIII) ; The Noble or Inert Gases.
The columns are called groups (or, sometimes, families). The rows are called periods.
periods are the rows and families are the columns
The elements in the same vertical columns, also called groups or families, all share common traits with each other (for example, all of the alkali metals react violently when placed in water.) This is because all of the elements in one group contain the same number of valence electrons.
Columns in a Periodic Table are called groups.They represent elements with similar characteristic. All the elements in a group has same number of valence electron.
The columns are known as groups.

All views contain rows and columns. The default view is called the Normal view.
