Why are the alkali metals and halogen among the most reactive elements on the periodic table?

because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)

Where are the most reactive element found on the periodic table?
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
What groups are the very reactive elements from?
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
What are two most reactive groups in the periodic table?
The two columns of elements in the periodic table that contain the most reactive elements are columns 1 and 17, the alkali metals and halogens respectively.
What are properties of the group of elements on the periodic table that have just one valence electron?
Apart from hydrogen, they are very reactive metallic (alkali) elements.
Which set of elements make up the reactive group of all metals?
The alkali metals in column 1 of most wide-form periodic tables.
What group of elements on the periodic table is most reactive?
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
The two most reactive groups of elements in the periodic table are the alkali metals and the what?
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
Where are the most reactive element found on the periodic table?
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
What family in the Periodic table contain the most reactive metals?
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
What groups are the very reactive elements from?
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
What are the highest and lowest reactive elements on the periodic table?
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..
Where on the periodic table are element most likely to react with other elements which direction?
The most reactive elements are alkali metals and halogens.
What are the most active groups in the periodic table?
Generally the most reactive elements in the periodic table are found in the first two (left-most) columns: the alkali metal and alkali earths.
What are the most reactive elements on the periodic table?
The alkali metals and the halogens are the most reactive groups and among them, francium and fluorine are the most reactive, especially with each other.
Which periodic table famiy is the most reactive?
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
What are two most reactive groups in the periodic table?
The two columns of elements in the periodic table that contain the most reactive elements are columns 1 and 17, the alkali metals and halogens respectively.
What metal is alkali metal?
This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D
