As you move left on the periodic table, the elements get more reactive and as you move down the periodic table. Using that thinking the most reactive elements are the Alkali Earth Metals (column 1) and the most reactive element is Francium. The least reactive are the noble gases in the last column- Helium, Neon, Argon etc..

TaigaThe highest reactive elements on the Periodic Table are the alkali metals located in group 1, such as lithium, sodium, and potassium. These elements readily lose their outermost electron to achieve a stable electron configuration.
The noble gases, located in group 18, are the least reactive elements on the periodic table. They have a full outer shell of electrons, making them very stable and unlikely to form chemical bonds with other elements.

How does the number of valence electrons in an atom relate to the elements placement on the periodic table?
When elements are on the same period they are most likely to have similar characteristics. Being that the periodic table is arranged from left to right, it is also arranged from lowest amount to highest. All the highest elements are together and all the lowest are together.
What is the most reactive of all the chemical elements?
The most reactive chemical element is fluorine. Reactivity of the elements increases as we go down and to the left on the periodic table, and it also increases as we go up and to the right on the table.
What is the least reactive group in the periodic table?
Noble gases, such as helium, neon, and argon, are the least reactive group in the periodic table. They have a full outer shell of electrons, making them stable and less likely to form chemical bonds with other elements.
Where are the lowest and highest atomic numbers found in the periodic table?
The lowest is 1 (Hydrogen) and the largest is 116 (Livermorium)
Can elements be ordered by there atomic number?
Yes, elements can be ordered by their atomic number. The atomic number of an element corresponds to the number of protons in an atom's nucleus, and elements are arranged in the periodic table from lowest to highest atomic number.
