Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Electronegativity is ____
A
how good an atom is at attracting electrons
B
the ability of an atom to lose electrons
C
the energy required to remove an electron from a specific atom
D
how easy it is to make friends.
Explanation: 

Detailed explanation-1: -Electronegativity is a measure of an atom’s ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

Detailed explanation-2: -Electronegativity is an index of the tendency of an atom to attract electrons. It is proportional to the difference between an atom’s ionization potential and its electron affinity.

Detailed explanation-3: -Electronegativity is the measure of the ability of an atom in a bond to attract electrons to itself. Electronegativity increases across a period and decreases down a group.

Detailed explanation-4: -The positively charged protons in the nucleus attract the negatively charged electrons. As the number of protons in the nucleus increases, the electronegativity or attraction will increase. Therefore electronegativity increases from left to right in a row in the periodic table.

Detailed explanation-5: -All elements are compared to one another, with the most electronegative element, fluorine, being assigned an electronegativity value of 3.98. Fluorine attracts electrons better than any other element.
