When you consider a periodic table, you think of aspects like oxygen, neon, lead, and iron. You may even believe of numbers, rows, and columns. You may not think of trends that are taking place throughout a periodic table. There are several trends that go on in a periodic table. The patterns that I am going to be explaining throughout this paper are atomic mass, atomic radius, first ionization energy, and electronegativity.
When you study a normal/ordinary table of elements, the atomic mass will usually grow when going delegated right and it will likewise get larger when you go leading to bottom.
The atomic mass grows delegated best and leading to bottom because the protons, electrons, and neutrons are increasing making the mass grow as you motion picture along the regular table.
When you look at the patterns of the atomic radius, you will see as you go left to right, the radius gets smaller and when you go top to bottom the radius grows.

The radius grows going leading to bottom due to the fact that more energy levels are becoming occupied by electrons. The radius gets smaller going left to right due to the fact that you are adding more protons which pulls the electrons and it makes it become out of balance.
If you take a look at the patterns of the first ionization energy trends on a table of elements, you will discover that as you go left to best it gets larger, and as you go leading to bottom it gets smaller sized.
This occurs because as you go to the right, you acquire more protons increasing the magnetic pull making it harder to lose electrons. As you go top to bottom it gets smaller due to the fact that as you go down, the electrons are farther away from the nucleus, which needs less energy than an aspect that has electrons closer to the nucleus. For example, Li is smaller sized than Cs. So if you attempt to take an electron from Li it will require more energy because this atom is smaller and the electrons are closer to the nucleus.
When you look at a periodic table you will notice the trends of electronegativity. As you go you left to right, the electronegativity gets bigger, but when you go top to bottom it gets smaller. This trend happens because as you move right the atoms have a tendency to gain electrons in order to become more stable. It gets smaller going top to bottom because you lose energy levels putting the protons out on the outer edge and making it easier to gain electrons.
Personally, I think that the periodic table that we use daily is easier to use because it makes sense, and it is organized in a neat manner. It also makes sense to me when I look at it. But, when I look at the alternative periodic table, it seems to have a few things that I like, but the way that it is organized does not really make sense to me. One way that the alternative periodic table is superior to the normal periodic table that we use daily is that it has all the sublevels in an order that is easier to understand and it also shows the way that the elements bond in each different sublevel.
It also has the period number which makes it easier to read and find each sublevel and period. Two ways that the alternative periodic table is worse than the normal periodic table is that the numbers aren’t in corresponding order, they are just scattered all over the place and it is harder to see the trends because the organization is not proper compared to the organization of the normal periodic table. Also, the alternative one does not show the atomic mass for each element.
