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...
The three formats are the old International Union of Pure and Applied Chemistry (IUPAC) table, the Chemical Abstract Service (CAS) table, and the new IUPAC table. The old IUPAC system labeled columns with Roman numerals followed by either the letter A or B. Columns 1 through 7 were ...
Periodic Table Groups NameDescription Group 1 (IA, IA)The alkali metals or hydrogen family/lithium family. Group 2 (IIA, IIA)The alkaline earth metals or beryllium family. Group 3 (IIIA, IIIB)The scandium family. Group 4 (IVA, IVB)The titanium family. ...
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 ...
table is color-coded to show the chemical groups, and each group is described in a panel of the same color. Other info panels describe atomic structure, chemical bonding, and radioactivity. It does not overload kids with a lot of detailed numbers, but it does provide some simple rules-of...
today. You can see Mendeleev's original table (1869). This table showed that when the elements were ordered by increasingatomic weight, a pattern appeared where properties of the elements repeatedperiodically. This periodic table is a chart that groups the elements according to their similar ...
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!
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 organization of elements can also predict the properties of unknown or newly discovered elements. 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...
