Those are groups.
It is called a Group. There are 18 groups in the modern periodic table.
the answer is groups.Added:There are 18 main groups and two special ones (with 14 lanthanides and 14 actinides respectively).Groups contain elements with the same 'outer' electron configuration (valence electrons).Note: Vertical rows are actually called: columns
The columns are called groups (or, sometimes, families). The rows are called periods.
The columns in the periodic table are called groups or families. These columns contain elements with similar chemical properties due to their shared number of valence electrons.
Colunms are named 'Groups'. Rows are named 'Periods'.
The columns are known as groups.
The columns are known as groups.
the vertical columns in the periodic table are known as groups.
There are 8 A columns on the periodic table. They are the two columns of the s-block and the six columns of the p-block.
the top to bottom are known as columns or groups
A row on the periodic table is known as a "period" and a column is known as a "group."
the vertical columns are known as groups
Horizontal rows in Periodic Table are called Periods
The vertical columns of a periodic table are called groups or families. They share similar chemical properties because they have the same number of valence electrons.
groups are the vertical columns on the periodic table
Vertical columns are known as groups.
The vertical columns of the periodic table are called groups or families.
