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..
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.
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.
Noble gasses (group 8) are the least reactive elements in the periodic table because they have a full valence shell.The right-most column, Group 8*, or the noble gases, is the least reactive elements in the periodic table.* In newer version of periodic table by IUPAC, its the group 18; whereas it was the 8th A group that noble gases occupied in older version.
The lowest is 1 (Hydrogen) and the largest is 116 (Livermorium)
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.
That would be the element with the highest atomic number but the lowest number of valence electrons.

the periodic tables are arranged by their Atomic Mass, from lowest (helium) to highest (not sure) all elements in the same column have the same number of valence electrons

Francium is the most reactive metal. Reactivity increases and you go down a family and decreases as you go across a period on the Periodic Table. Francium is the farthest left and the lowest so it is the most reactive.

It turns out that fluorine is the most reactive element. It is at the top of the Group 17 elements, the halogens. And they are, as a group, the most reactive group on the periodic chart.
The Periodic Table of elements has gone through several arrangments, but the current (and correct) arrangement goes from lowest to highest atomic number (number of protons). i.e. Hydrogen has 1 proton, Helium has 2 protons, etc.
The gas element found in group 18 of the periodic table is helium. It is a colorless, odorless, and non-reactive gas that has the lowest boiling point of all the elements. Helium is commonly used in balloons, airships, and cryogenics.
