Question 15

the most unreactive group of elements is the

a)halogens

b)noble gases

c)alkali metals

d)transition elements

The group 18 elements which are called as B) Nobel gas are the most unreactive elements present in the periodic table.

Explanation:

Group 18 components are nonmetals and are called Nobel gases. They are for the most part drab and unscented gases. Their external vitality level is likewise full, so they are the least receptive components. In nature, they only occasionally consolidate with different substances.  

Group 17 are called halogen. They are profoundly receptive nonmetals with seven valence electrons. They respond fiercely with soluble base metals, which have one valence electron. The two components join to shape a salt.

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
