Which element below is least reactive? Which element below must be stored in oil because of its reactivity?
Answer: helium. sodium
The ability of an atom or element to undergo chemical changes is referred to as reactivity. Sodium is a highly reactive element that is stored in kerosene oil. And the one that is least reactive is helium. As a result, the correct options are A and C respectively.
What is reactivity?The ability of an element to form a new substance through chemical reactions is referred to as reactivity.
They have the ability to easily displace another element from reactions. Alkali metals in Group I are highly reactive elements that should be kept away from water and air.
Sodium is an alkali metal that must be stored in kerosene oil because it is highly reactive with oxygen and water, releasing large amounts of heat in an exothermic reaction.
Kerosene, on the other hand, is a hydrocarbon that does not react with a sodium atom.
Also, as the helium is a noble gas, so is least reactive when it comes to reactivity.
Thus, the correct options are A and C respectively.

Answer:
D) Territorial Behavior
Explanation:
EDG 2022
The reason that is not for cluster distribution of organisms is Territorial behavior. The correct option is d.
What is cluster distribution?Biogeography is the study of organisms' geographic distribution patterns and the factors that influence those patterns.
A distinct grouping of neighboring values in a numerical variable distribution that occur noticeably more frequently than values on either side of these neighboring values.
If a distribution contains two or more clusters, they will be separated by places where values are thinly distributed or absent.
Individuals in patches have a clumped distribution, also known as an aggregated distribution.
This can happen if resources are distributed unequally; for example, pipevine swallowtail caterpillars may congregate in areas with California pipevine, their host plant.
Territorial behavior is the reason that this is not true for cluster distribution of organisms.
Thus, the correct option is d.
