The ionization energy is lower down in the group.

What is the most reactive group of elements in the periodic table?
Alkali Metals (group 1) because they only need to lose one electron in order to have a stable valence level of 8. As you go down the alkali metals group, the elements become more reactive. So Francium is the most reactive alkali metal. Also, Halogens, because they already have 7 electrons and only need to gain one in order to have a stable valence level of 8. As you go up the halogens group, the elements become more reactive. So Fluorine is the most reactive halogen. This is just a brief summary, if you want to know the reasons why this is I suggest you search about ionization energy, electron affinity, and electronegativity because these are all what make an element "reactive."
Why do alkali metals become more reactive as you move down periodic table?
It is easier for them to lose the atoms basically and they bacome more vulnerable so when reacted with water they lose their charged particles and react violently
Is it true that the most chemically reactive metals are in group 1 of the periodic table of elements?
Yes. The most chemically reactive metals are in group 1. To add to that, as you go down the periodic table, in group 1, they become more reactive. Potassium is more reactive than Sodium, and Cesium is more reactive than Rubidium. The same general trend occurs throughout the periodic table. The lower down you go in any given column, the elements are more reactive than the last, and the further left you go in each row, the elements are more reactive than the last. (There are exceptions however.) It has to do with electronegativity.
Which group on the periodic table would be the most reactive?
Really, the most reactive elements on the periodic table tend to be found in the Halogen Group. But the alkali metals are just as reactive. In fact solid sodium will even explode in water!Group 1 has the most reactive metals and the most reactive non metals are located in group 17.
Why metals become more reactive as you move from left to right across the periodic table?
They don't
What is the reactivity of caesium?
Caesium is the 5th element in group I of the periodic table. It is an alkali metal, and they become more reactive as you go down the group from lithium to sodium to potassium etc. So we would expect that caesium is highly reactive, even more reactive than rubidium.
What is the least reactive metal in the alkali metal group?
Lithium - As it is first in Group 1. Group 1 elemts become more reactive as you go down the group.
What is the more reactive metal Cs or Na?
'Cs' ( Caesium )is the more reactive metal. Both metals are in Groujp (I) , The alkali metals. On going down from lithium to francium , group(I) metals become more reactive.,
Why is chlorine is so reactive?
Chlorine's structure makes it very reactive (it is in group VII of the Periodic Table and therefore needs to gain one electron in order to become stable)!
How do the properties of each family of metals change as you move across the periodic table?
They become less reactive.
What does Li Na and K have in common?
Lithium, sodium and potassium are all group I elements. They are also called alkali metals. They react violently with water to form strongly alkaline solutions. The elements, as we descend the group in the periodic table, become increasingly reactive.Li Na K are alkali metals. They are present in group-1. They have one valence electron.All of these elements are located in group 1 of the periodic table. Each of these elements are highly reactive metals. They react with acids to produce salts. All of these are good conductors of electricity and heat.Li,Na and K are in the 1st group of the periodic table. They are alkaline metals. They all have a valency of 1.
Do metals become more reactive as you move from left to right across the periodic table?
In the alkali metals and the alkaline earth metals (groups IA and IIA on the periodic table), all increase in reactivity as one goes down the columns. These elements react by loaning out electrons, and it is easier to loan out an electron if the valence band where that lone electron (group IA) or two (group IIA) hangs out is farther from the nucleus and is screened by other (more) electrons in lower bands. The elements farther down the columns are more reactive because they can more easily loan out electrons. Just as an aside, one might expect that the elements that borrow electrons might be better able to do that if there was less electron screening, right? And that would suggest that the elements higher in the columns of the groups that are seriously interested in borrowing electrons (think group VIIA) would be more reactive than the lower ones, wouldn't it? Maybe that's why fluorine is called the hungry wolf of the periodic table.
