Group/Period Trends

Postby Jeffrey Doeve 2I » Sun Nov 01, 2020 12:51 pm

I was wondering if when we were classifying trends, would we typically always prioritize the vertical direction over the horizontal direction? My logic is that an additional shell plays more of a role in the trends of a periodic table than differing nuclear charges.

From my understanding, vertically is prioritized because of the additional shells in the cases of atomic radius and ionization energy, but electron affinity has more to do with filling the shells than periodicity.

I learned throughout high school to prioritize the vertical vertical direction!

I believe the groups have more in common than the periods. Each vertical column has its own name and the atoms in the column act in a somewhat similar way (i.e. noble gases).

Like some of the other students, I also learned in high school to prioritize the vertical direction because there are fewer elements in each group vs a period, which have more shared characteristics.

As everyone previous to me, I also say to prioritize the vertical over horizontal just because it gives you more information about the element as well.

Vertical gives more information, and going up or down loses and gains an entire shell, respectively. This extra chunk of space that the atom now takes up do to the extra shell would much more definitively tell us what will happen rather than a one or two valence electron change.

As the others previously stated, I also learned to prioritize the vertical trend over the horizontal trend due to the less amount of elements in a group compared to a period.
