the vertical columns are known as groups whereas the horizontal rows are known as periods.

The elements in the periodic table are arranged in order of increasing atomic numbers.
The organization of the periodic table in terms of conductors of electricity could also be said to be the organization of the periodic table in terms of metallic character, since metals are the best conductors of electricity. Metallic character decreases across a period and increases down a group.
Flourine is the most electromagnetic element on the periodic table.
Because its atomic number is what it is. The Periodic table of elements was arranged so that the scientist could easily scan it and identify an unknown substance by its atomic number or number of protons. In uncomplicated terms, Neon (Ne) has one less proton than Sodium (Na), but one more than Fluorine (F).
Group: a vertical column Period: an horizontal row
They are groups

The halogens. These are group 17 using the modern numbering system of the groups on the periodic table.
In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
The horizontal rows are called Periods. There are 7 periods in periodic table.
The elements in the periodic table are arranged in order of increasing atomic numbers.
Usually when saying "periodic," scientists usually refer to the periodic table. This table is the shortened version of gasses, solids, liquids, and so on.
The organization of the periodic table in terms of conductors of electricity could also be said to be the organization of the periodic table in terms of metallic character, since metals are the best conductors of electricity. Metallic character decreases across a period and increases down a group.
The elements phosphorus and sulfur are elements 15 and 16 on the periodic table. They will have more in common than sodium, element 11 and an Alkali metal from Group 1 of the table, will have with either phosphorus or sulfur.

You can use CSS to define elements and place those elements in a table configuration. The other option would be to create an HTML table. Fill the table cells with the data and leave cells blank to display the spaced on the table that do not include elements. You can see a periodic table HTML code by going to chemicool dot com and viewing the source.
