The horizontal rows of the table are called periods. The elements of a period are characterized by the fact that they have the same number of electron shells; the number of electrons in these shells, which equals the element's atomic number, increases from left to right within each period....

Electron Configuration Shorthand: For elements in groups labeled A in the periodic table (IA, IIA, etc.), the number of valence electrons corresponds to the group number. Thus Li, Na, and other elements in group IA have one valence electron. Be, Mg, and other group-IIA elements have two...
Along the left side of the table, I labeled the rows alphabetically. (**This is optional but helps younger kids who are uncomfortable pronouncing the names of the elements yet.) They already have row numbers along the top. Laminating makes it re-usable! I used two file folders and hooked ...
calledgroups. Groups are labeled at the top of each column. In the United States, the labels traditionally were numerals with capital letters. However, IUPAC recommends that the numbers 1 through 18 be used, and these labels are more common. For the table to fit on a single page, parts ...
The vertical columns are called Groups and the horizontal lines, Periods. The members of a Group have the same outer electron configuration but different quantum numbers at that outermost level. Within the table a number of blocks are labeled in terms of the nature of the orbital occupied by ...
There are seven rows (periods), 18 columns (groups), and four blocks in the periodic table. Groups are numbered from 1 (leftmost column) to 18 (rightmost column). The blocks are labeled the s-block, f-block, d-block, and p-block. The elements are also grouped into metals, metalloids...
1 through 18, are called groups. In the periodic table, elements with similar chemical properties are in the same group. The horizontal rows of the periodic table, from 1 to 7, are called periods. Periods correspond to the number of electron shells possessed by atoms of the elements in tha...
Take a moment to see how the above image relates to the complete periodic table, which we reproduce below. Each row that begins with H down through Fr corresponds to a period; in this table, there are seven periods. Each column, labeled with small blue numbers 1-18 along the top of th...
