all atoms want a full ring of outer electrons, in the first ring this is 2 in the second this is 8, for the others it's slightly more complex. A groups group number tells you how many elactrons in has in the outer shell. Group 8 already has a full outer ring of electrons so doesn't react with others. The rest need to share, gain or lose electrons for example Lithium is in group one it needs to lose a electron to have a full outer ring Fluorine is in group 7 so it wants an elctron so they react together and Lithium gives it's electron to Flourine.

Which 2 groups are the most reactive on the periodic table why?
they
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 the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
Where are the most reactive metals located on periodic table?
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
What groups are most reactive on the periodic table?
group 1 and group 17 are the most reactive groups
What is the most reactive groups of metals in the periodic table?
the alkali metals are the most reactive... either cesium or francium would be the most reactive out of this group.
What group is 1?
in the Periodic Table it is the most reactive metals!
What are the most reactive groups of nonmetals on the periodic table?
The most reactive group of non metal is group-17. It is called halogen family.
Are the most reactive metals in the middle of the periodic table?
No, the most reactive metals are typically found on the left-hand side of the periodic table, in groups 1 and 2. These metals, such as alkali metals and alkaline earth metals, readily lose electrons to form positive ions.
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.
What is the least reactive groups on the periodic table?
Noble gases are least reactive because they have a full shell
How does reading across a period the periodic table compare with reading down a group of the table?
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
In which family in the periodic table are the most reactive nonmetalsmily in the periodic table are the most reactive nonmetals?
halogenes/non metals
