Q:

Which of the following elements has the highest electronegativity?

A) Chlorine B) Bromine
C) Fluorine D) Helium
 
Answer & Explanation Answer: C) Fluorine

Explanation:

Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. The higher the value of the electronegativity, the more strongly that element attracts the shared electrons.

Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element and lithium is the least.

Q:

Which of the following elements has the lowest electronegativity

A) Bromine B) Fluorine
C) Carbon D) Lithium
 
Answer & Explanation Answer: D) Lithium

Explanation:

Electronegativity is the tendency for an atom to attract electrons. There are general trends on the periodic table which you can use to determine the relative electronegativity for different elements, but otherwise you can also look at their valence shell and effective nuclear charge to determine their relative electronegativity.

 

Here from the given options, Lithium has least tendency to attract electrons and thus has a lower electronegativity.
