The elements in the first group of the period table which have one electron in their outer shells and react extremely well are also known as the alkali metals. These elements are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
Actually, the answer is Alkaline-earth Metals. They are slightly less reactive than alkali metals. They are silver colored and more dense than alkali metals.
Elements in the second group of the Periodic Table have 2 outer shell electrons and are also very reactive What are they called?
The elements are called ALKALIS which are present in first group and has one outer shell electron and is extremely reactive.
Alkali Earth metal
alkaline earth metals
Alkaline earth metals
This group is called "Alkali metals".
Apart from hydrogen, they are very reactive metallic (alkali) elements.
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
The most explosive element is Francium, located on the bottom left hand corner on the Periodic Table of Elements. It is extremely reactive, as it wants to "give" away one electron to become stable.
because they are extremely reactive. They belongs to group of one periodic table and have one electron in the outer valence shell.
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
These elements all want to lose 1 electron to have a noble gas electron configuration and are thus extremely reactive, particularly with water.See the Related Questions to the left for more information about the Group 1 alkali metal elements.
Apart from hydrogen, they are very reactive metallic (alkali) elements.
It is in Group 17 that you will find the most reactive elements. These elements all lack only one electron from having that "magic" electron configuration of the inert gases. That makes these elements very "hungry" to get that "last electron" so their electron structures become more stable.
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
They are all reactive metals with one valence electron in their outermost s sublevel.
The most explosive element is Francium, located on the bottom left hand corner on the Periodic Table of Elements. It is extremely reactive, as it wants to "give" away one electron to become stable.
Yes, fluorine is the most reactive element on the periodic table.
elements in group 17 need one more electron to attain the nearest noble gas configuration, hence they are more reactive
because they are extremely reactive. They belongs to group of one periodic table and have one electron in the outer valence shell.
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..
Metals are more reactive elements.
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
