groups and famalies
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 two names for horizontal rows on the periodic table are periods and series.
Periods and the vertical columns are groups
The Periodic Table has 18 groups and 7 periods.
As in any two dimensioned table (Rows and Colomns) each particular element1) is in one 'Cell' at the croccing of R's and C's. 1) An element can be 'chemical' in the periodic table or 'numerical' in a calculus table, or mixed in an accounts 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

A more accurate periodic table includes 118 elements, organized into 18 columns. These columns represent groups of elements with similar chemical properties, allowing for easier comparison and analysis.

In the periodic table of the elements there are 7 periods and 18 groups. The rows are called periods and columns are called groups. You may be getting confused by the lanthanides and actinides. These groups of elements are found in two rows at the bottom and seem to not be a part of the table. However, if you find and extended version of the table you will see that, technically, these two rows belong in Periods 6 and 7.
the group and the family. the groups are the rows going from left to right and the families are the columns going from top to bottom.
There is no symbol KM in the periodic table.

A solid could be ice, and most metals like iron which are found in columns three through twelve on the periodic table. Some gases include hydrogen, oxygen, nitrogen, and carbon. Gases can be found on the last two columns to the right on the periodic table (columns 17 and 18).
