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 18 vertical columns, or groups, in the standard periodic table. At present, there are three versions of the periodic table, each with its own unique column headings, in wide use. The three formats are the old International Union of Pure and Applied Chemistry (IUPAC) table, the C...
The periodic table gets its name because it includes categories of elements that repeat themselves periodically and predictably. When you look at a periodic table (see Resources for an interactive example), you can see that it has some curious gaps in the rows at the top but that these disapp...
1.2.1.2 The Periodic Table The periodic table is an organisation of elements arranged in increasing atomic number into a series of columns (groups) and rows (periods). The classification was chosen to emphasize the periodic nature of the chemical properties (http://www.webelements.com/; Figure...

(fuzzy clouds), which is close as you can get to visualizing what an atom really looks like. The orbitals are labeled. It describes other ways to visualize atoms, namely, electron orbits (like planets) and surfaces of constant probability (bulgy blobs). It has a small periodic table ...
As we will see shortly, this turned out not to be the case, but Mendeleev was indeed correct to group these two elements as he did.Notice that there are several places in the table that have no chemical symbol, but are instead labeled with a question mark. Between zinc (Zn) and ...
You quickly scan the room, looking for your friends to sit with. Depending on how social or introverted the guests are, you might be able to figure out the friends groups just by looking at the guests at each table. This scene gives a simple way to understand how “clustering” looks ...
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 ...
