Including the design and management of gardens.

Explanation

In moving down to the halogen group E.N. decreases hence Iodine has the lowest electronegativity.

DETAIL ANSWER:

 iodine has the lowest electronegativity.

Fluorine has the highest electronegativity followed by chlorine and bromine,

and then with the least reactivity, we have iodine, among the given options.

Hence, option D is correct.

Note: The noble gases i.e. group 18 elements have no electronegativity.

Explanation

A reaction in which heat is absorbed is called an endothermic reaction.

These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

Explanation

As you move from the equator towards the poles, the latitude increases (up to 90 degrees).

The further you go from the equator in any direction,

the difference between the duration of the day and night at different times of the year will be bigger.

Additional information 

there are two points in the year when day and night are approximately equal in duration. 

This is called an equinox.

The equinoxes occur around:

• March 20th-21st 
• September 22nd-23rd each year.
