How do the rows of the periodic table affect an element's behavior in a chemical reaction? I know that the columns of the periodic table determine the number of valence electrons in an element, and the number of valance electrons in an element determine that element's stability. Do the rows of the periodic table determine the behavior of an element in a chemical reaction?

Thanks in advance!

Rows of elements are called periods. The period number of an element signifies the highest unexcited energy level for an electron in that element. The number of elements in a period increases as you move down the periodic table because there are more sublevels per level as the energy level of the atom increases.

If you look at the periodic table, ionization energy tends to decrease as you move down a column and increase as you move across a period from left to righ
Like ionization energy, electronegativity decreases as you go down a column and increases as you go across a period from left to right................

so the chemical reactions are effected due to electonegtivity and ionization energy in several ways...

Any way its physics section.. please post these question in chemistry section.

Thanks a lot! And I wasn't really thinking about the category. I guess I put it there because this question has to do with my Physical Science.
