The elements in the Periodic Table are organized by atomic number, from left to right (and reading top to bottom), in increasing order. They also, for the most part, increase in molecular weight.
Each group (or family/column) behaves similarly because of the same number of valence electrons.
Group 1 are alkali metals (valence +1).
Group 2 are alkaline earths (valence +2).
Group 3 include some transition metals, as well as the lanthanides and actinides).
Groups 4 - 12 (under new IUPAC numbering) are the transition metals.
Group 13 is the boron group and, except for aluminum, starts a stair-step group of elements diagonally to the right, which form the metalloids (important in semiconductors).
Group 14 (old Group 4) are the tetravalent elements (such as carbon) (valence 4).
Group 15 (old Group 5) are the nitrogen group nonmetals (valence 5, -3).
Group 16 (old Group 6) are the oxygen group nonmetals (valence 6, -2).
Group 17 (old Group 7) are the halogens (valence 7, -1).
Group 18 (old Group 0) are the noble (rare or inert) gases.
Also, each row in the Periodic Table corresponds to the outermost principal quantum number of the elements in that row.
In terms of orbital arrangement:
Groups 1 - 2: s block
Groups 3 - 12: d block
Lanthanides and Actinides: f block
Groups 13 - 18: p block
