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.

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 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 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.
Where are less reactive metals nonmetals and metalloids on the periodic table?
in groups 1 and 2 :D
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.
Is selenium reactive?
yes, it is a non metal and it is placed on the right side of the Periodic Table, reactivity increases from left to right on the periodic table. since selenium is in group 16 out of 18 groups, it is a very reactive element. hope this helps you!
How does the periodic table makes life easier?
Periodic table groups elements with same properties together. It makes the study of elements easier.
The most reactive nonmetals on the periodic table are?
The most reactive nonmetals are the halogens in group 17 of the periodic table.
