The periodic table houses noble gas elements in group 18. these elements are highly stable and rarely react with any other elements. what is one possible reason for the stability of the noble gas elements? a. they easily form covalent bonds. b. the compounds that they form with other elements are very unstable. c. their outermost shell has the maximum number of electrons that it can hold. d. they require less activation energy.

i was doing some research and it "b.The compounds that they form with other elements are very unstable."

i hoped this helps a bit but if im wrong please dont report me brainy might remove my account. im trying my best to answer questions correctly

Option (C).

Explanation:

Noble gases are included in Group 18 of the modern periodic table. The noble gases are least reactive and most stable elements of the periodic table.

Noble gases has fully filled electronic configuration. Their outermost valence shell electrons are fully filled, they do not lose or gain any electron and neither they share electrons with other element. The maximum electrons are present in their outermost shell that makes the noble gases least reactive and more stable in nature.

Thus, the correct answer is option (C).

we would need to see the picture to answer it

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
