Which are the most highly reactive metal elements?
The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.
Which is more reactive O or S?
Explanation: oxygen is only more reactive than sulphur because due to small atomic size oxygen atom has high tendency to attract the electrons ( more electronegative .
What do you mean by reactive elements?
reactive elements are the the elements which are ready to gain electrons coz they have incompletely filled outermost shell.
Is Ne or F more reactive?
Among the halogens, fluorine, chlorine, bromine, and iodine, fluorine is the most reactive one. It forms compounds with all other elements except the noble gases helium (He), neon (Ne) and argon (Ar), whereas stable compounds with krypton (Kr) and xenon (Xe) are formed.
Is oxygen more reactive than selenium?
Oxygen, sulfur and selenium are all group 16 elements. Hence, we can conclude that out of the given options element oxygen is more reactive than the others.
How do I know if an element is reactive?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
Is potassium a reactive metal?
Pure potassium is a highly reactive metal. Exposed to water, it explodes with a purple flame, so it’s usually stored under mineral oil for safety.
Which grouped of elements is the least reactive?
Answer and Explanation: The noble gas group is the group of elements that are the least reactive. The noble gases are the last column on the right side of the periodic
Which family of elements is the least reactive?
3 Answers. Elements of the group 18 of periodic table, known as noble gases are the least reactive family of elements. The six naturally occurring elements in this group are helium, neon, argon , krypton , xenon and radon.
What group of elements are very reactive metals?
Group I consist of alkali metals and these are very reactive. They rapidly react with oxygen so they should be stored out of contact with oxygen to prevent the oxidation process. By moving down the group reactivity is increased. The less reactive metals such as sodium potassium and lithium are stored in the oil to prevent the reaction of oxidation.
Which metal is the least reactive?
Elements with the Lowest Reactivity. The least reactive element is helium, which forms no compounds. The least reactive metal is platinum. Platinum cannot be oxidized in air, even at high temperatures. It is unaffected by common acids, although it can be dissolved in aqua regia (a mixture of nitric acid and hydrochloric acid in the ratio 1:3)…
