Best Answer

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..

The 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.

What are the most reactive elements?

That would be the element with the highest atomic number but the lowest number of valence electrons.


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.


How are tables arranged?

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


How are Periodicals arranged?

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


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.


What is the most active metal on the periodic?

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.


Which element is the most reacitve?

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.


Is the periodic table arranged?

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.


What is the gas element found in group 18 of the periodic table?

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.
