If I recall correctly, it's because they don't have any electrons in their atoms. Atoms react in order to get a full set of 8 electrons, and the less electrons an atom has, the more likely they are to react.
What else can I help you with?
Which group is the most highly reactive metal group?
Group 1, the Alkali Metals, which are extremely reactive.
Most reactive group in periodic table?
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
Is it true the most chemically reactive metals are in group 1 of the periodic table?
yes the most chemically reactive elements are in group 1
What groups are most reactive on the periodic table?
group 1 and group 17 are the most reactive groups
Is the most chemical reactive metal in group 1?
Francium (Fr) is the most reactive metal.
What kind of group one are the most reactive?
The elements in group 1 become more reactive as you go down the group.
In the periodic table which group of element are the most reactive?
group 1
Would a metal in Group 13 be more or less reactive that a metal in Group 1?
less reactive.beacuse group-1 elements are the most reactive elements.
What group is 1?
in the Periodic Table it is the most reactive metals!
Which of the elements in Group 1 are the most reactive?
it is caesium.
The most reactive element in group 1?
Francium.
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.
