Is krypton the most reactive?
We can see from a periodic table that krypton has a filled valence shell, since it is in group 18 and on the far right of the periodic table. Group 18 is known as the noble gases. Therefore, bromine is more reactive than krypton.
Which element is most reactive?
Alkali metals (situated far away from transitional metals and noble gases) are the most reactive elemental group. Cesium is second from the bottom of this group, with 6 electron shells, so it fits all the characteristics of a reactive atom, therefore making it the most reactive element.
Is krypton or xenon more reactive?
Krypton is less reactive than xenon, but several compounds have been reported with krypton in the oxidation state of +2.
Is krypton reactive or nonreactive?
Or not.) Krypton (Kr, Z=36). Krypton is a colorless, odorless, unreactive gas which liquefies at -153.2°C (119.9 K).
Why is sodium less reactive than?
Sodium atoms due to being smaller in size have high ionization energy and thus, it can’t lose electrons easily and is more stable and less reactive. Hence, from this it is clear that sodium is less reactive than potassium.
What’s more reactive lithium or sodium?
Reactivity of Group 1 and 2 elements increases as you go down the periodic table. So sodium is more reactive than lithium.
Which one is more reactive lithium or sodium?
Answer: Sodium is more reactive than lithium because sodium is larger in size. Outermost electrons are less tightly held in sodium than in lithium. As a result, sodium loses its outermost electron more easily than lithium.
Which element is more reactive potassium or Krypton?
Krypton is more reactive than Potassium because it has a full outer shell. Potassium (K) and Krypton (Kr) are in the same group, so they have the same number of valence electrons. Potassium is more reactive, because it has less electron shells than Krypton.
Is fluorine more reactive than sodium?
One could ask which element is the most reactive with Sodium? The answer then is Fluorine, not Caesium.
