These elements are the most reactive because of the number of electrons floating around them. To put it simply, small numbers of electrons want to join with other electrons, so when a layer of few electrons can join with an almost full layer of electrons to make a full layer, it does, and sometimes violently.

∙ 13y agoMetals react primarily by donating electrons to other types of atoms. This process requires less energy in metals near the bottom of the Periodic Table because the valence electrons in these metals are in outer shells, further from the attraction of the nuclei and therefore less strongly bound into the metal atoms.

∙ 11y agoDown a group, the size of an atom increases, the attraction between the nucleus and the valence electrons and hence the ionization energy increases and it forms cations easily. Or in other words, down a group the electropositivity increases.
Electropositivity is a measure of an element's ability to donate electrons, and therefore form positive ions (cations).

∙ 11y agoColumns of the periodic table are ordered by valence electrons. Valence electrons are the number of electrons in an atom's outer shell, and they determine the reactivity of an atom. The first column contains atoms that have one valence electron, and thus need seven more electrons to become stable (to become stable, the outer shell must contain 8 electrons). This means that atoms with only one valence electron can make multiple bonds to other atoms, making them extremely reactive. The same applies to atoms in the second column.

∙ 12y agobecause their ionization potential is very low.they have high tendency to lose electron and reacts with others
Wiki User
∙ 13y agoIn general: Low-Left (Cs) and Up-right (F) are the most reactive elements.

∙ 11y agoBecause they are less reactive the can be found in the ground, in rivers, etc because they won't react with other substances such as water or gases in the air.

Should caesium element 55 be more or less reactive than potassium?
more reactive, the elements of the first column increase in reactivity as you go down
Which elements are most likely to react with other 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.
Difference between s-block metals and d-block metals?
the s-block elements are highly reactive elements, on the other hand, d-block elements are less reactive than the alkai metals and the alkai-earth metals. some are so reactive that they do not easily form compounds.
Why group 7 elements get more reactive as you go down the group from fluorine to iodine?
There can not be any reason, because the premise is not true: Group 7 elements become less rather than more reactive from fluorine to iodine.
What group of elements consists of non reactive non metals?
Non-reactive elements or compounds are called inert. This is a bit misleading, however - anything can be made to react given the right circumstances. The noble gases are about as close as you can get to truly inert, but even they will react under extreme conditions. >>M.T.<<
Is noble gases metals that are more reactive than the transition elements but less reactive than the alkali metals?
No, the noble gasses are nonmetals that are less reactive than all other elements.
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.
Should caesium element 55 be more or less reactive than potassium?
more reactive, the elements of the first column increase in reactivity as you go down
What can less reactive metals be found as?
Less reactive elements are more likely to be found uncombined, that is as the element rather than as part of a compound. This is usually called being 'found native'. For instance gold mines contain actual pieces of gold, whereas an iron mine usually contains something like rust, which has to be converted by a chemical reaction to obtain the metal.
Are the elements in group 18 reactive?
all the elements of group 18 are Nobel gases. They are very very less reactive.
What elements bond with iodine?
it bonds with many elements but it is less reactive than the rest of the halogens
Are groups 1 and 2 more or less reactive in periodic table?
Group 1 elements are the most reactive among metals, followed by group 2 elements.
Which elements are most likely to react with other 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.
Difference between s-block metals and d-block metals?
the s-block elements are highly reactive elements, on the other hand, d-block elements are less reactive than the alkai metals and the alkai-earth metals. some are so reactive that they do not easily form compounds.
What metal is more reactive than lead but less reactive than zinc?
In between these two, there are nickel, tin lead and hydrogen.They all are more reactive than copper but less reactive than iron.For your convenience, here is the reactive series of elements in order of decreasing reactivity:-Potassiumsodiumbariumcalciummagnesiumaluminiummanganesezincironnickeltinleadhydrogencoppermercurysilvergoldplatinum
Would a metal in group 13 be more or less reactive than in group one?
Group 1 will be more reactive than group 13 elements
What very unreactive metals are found in the ground?
Whether the elements found in the ground are reactive or not, partly depends on whether there is any other chemical there for them to react with.Gold, Platinum, Tin, and a few others close to the noble metals are less reactive, but even some reactive elements are found (uncommonly) in the native state.Silver is one of the more common ones so found, but Iron and Mercury are also found in the native state.
