The elements that have the most similar chemical properties are those in which are in the same group, or column on the Periodic Table.
~Periodic Table of Elements~
The Periodic Table of Elements is a chart arrangement of the chemical elements that display them in rows horizontally in ascending order of atomic numbers, as well as vertically according to the similarity of the chemical properties of their atoms. The position of an element on the table gives us further detail regarding the structure and chemical properties each element is built on.
- Examples of Elements with Similar Chemical Properties
- Lithium (Li) and Magnesium (Mg) → Both are metal elements which have similar polarizing power and electronegativity, as the "charge/radio" of both- are also the same.
- Beryllium (Be) and Aluminum (Al) → Both are rendered passive by the usage of nitric acid. These two elements are also considered metals and they form covalent bonds with their respective atoms. They both have distinctively low melting points, and the hydroxides and oxides of these two elements are both highly amphoteric by nature.
- Boron (B) and Silicon (Si) → Both are semiconductors, they form halides that are hydrolyzed in water and have acidic oxides. Such a relationship occurs due to the crossing and descending the periodic table have opposing effects.
Not only these pairs of elements, however there are many other pairs of elements that also share similar chemical properties. If you are still curious about chemical properties, the Periodic Table, and the elements within it, I would highly recommend that you look further into it. All of it is very interesting!
