Question

The elements with highest electronegativity is:
A. C
B. Si
C. Ge
D. Sn

Answer 1

Hint- We use basic theory to give answers to this question which are related to the periodic table. The symbol of Electronegativity is represented by symbol X which describes the tendency of an atom to attract a shared pair of electrons towards itself.

Complete answer:
In a molecule, the tendency of an atom to attract the shared pair of electrons towards itself is known as electronegativity. The most commonly used scale of an electronegative was designed by Linus Pauling. As we know that the value of electronegativity decreases as we move down the group
It refers to the ability of an atom to attract shared electrons in a covalent bond. Electron attracts the shared electron more strongly when the value of electronegativity is higher. Jons jocob Berzelius is the person who introduced the term electronegativity in 1811.

Electronegativity across the periodic table:
Electronegativity increases if you move across the periodic table from left to right and the value of electronegativity decreases as we move down the group
The most electronegative element on the periodic table is fluorine and the electronegativity value is 3.98 and the least electronegative element.is cesium with a value of 0.79. Metals have electronegativities less than 2.0. Those elements which require very few electrons to complete their valence shells and having the least quantity of inner electron shells between the positive nucleus and the valence electrons, are the higher electronegative.
So, we say carbon has the highest electronegativity in all group 14 elements of the periodic table.

Therefore, option (A) is the correct answer.

Note- The opposite of electronegativity is electropositivity: a measure of an element's ability to donate electrons. I.e. It is the measure of the ability of elements (mainly metals) to donate electrons to form positive ions. Those elements which can easily accept electrons to form negative ions are called electronegative elements, for example: non-metals.
