What are Periodic Trends ? by Ella

Periodic trends are specific patterns that you can find in the periodic table. In this patterns you can see the different aspects of a certain element, like its size and its electronic properties. The electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic are characteristics of the periodic trends. Periodic trends, are arranged based on how the position of elements are on the periodic table. It's easy to predict an element's properties with it, they exist because they have similar atomic structures of the elements like group families or periods. 

So why periodic trends are so important ?

Periodic trends are important because you are able to quickly predict an element's general properties. For example, the trends tell us what the largest atoms are, the most metallic elements,and the lowest ionization energies are in the lower left corner of the Periodic Table.

The smallest atoms, the most non-metallic elements, and those with the highest energies are at the upper right.

We also expect to see a change in properties as we go from left to right in a period or from top to bottom with a group.

I hope that I helped and at the same time made you interested on this amazing part of chemistry, but I have one more questions for you guys, which characteristics of the periodic table has the higher energy?
