False.
The vertical columns are called groups
The horizontal rows are called periods
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 horizontal rows on the periodic table are periods. Groups are the vertical columns on the periodic table.
The horizontal rows on the periodic table are called periods.
The horizontal rows on the periodic table are periods. Groups are the vertical columns on the periodic table.
No,Each of the columns in a periodic table represents a group.
false The vertical columns are known as groups whereas the horizontal rows are known as periods.
No; the periods are the horizontal rows. The vertical columns are called "Groups".
The vertical columns are called "Groups''The horizontal columns are called "Periods"The vertical columns of the periodic table are known as groups.
False. The vertical columns are known as groups whereas the horizontal rows are known as periods.
The vertical "rows" are called Columns, and the horizontal "rows" are called Periods
Vertical columns are called groups. Horizontal rows are called periods.
They are called periods because after each period in the following period elements are ordered according to their properties at the intersection with vertical columns (groups) and these properties are periodically reproduced.
Vertical columns are called groups. Horizontal rows are known as periods.
The horizontal rows on the periodic table are periods. Groups are the vertical columns on the 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
