What trend is seen on the periodic table?

Answer 1

"Electronegativity"

Answer 2

There are a number of trends in the table, some of them are:

* As you go from left to right the ionization energies generally increases, and as you go from top to bottom, in general, the ionization energies decrease.

* In general, as you move down and from right to left, the atomic radius increases. * As the atomic number increases, the molecular weight increases.

* The first period contains the most reactive elements and the final period contains the most stable elements.

* The Periodic Table is also aranged into blocks, the S, P, D and F blocks. These represent different orbitals. The first two periods make up the S block, the transition elements (periods 3-10) make up the D block, periods (13-17) make up the P block, and finally the inner transitional elements located at the bottom of the table make up the F block.
