Which one of the following has the highest electronegativity
Which one of the following has the highest electronegativity
The correct option is B Cl
If you look at the question carefully, you can see that, in periodic table,
Si, P and Cl belongs to same period (3rd) and Br is just below Cl.
If we look at the trend of electronegativity,
In a period moving from left to right, the electronegativity increases due to the increase in effective nuclear charge.
In a group moving from top to bottom, the electronegativity decreases because atomic radius increases.
because Electronegativity may be defined as the tendency of an atom to attract shared pair of electrons of bond towards itself in a covalently bondedmolecules.
In a period moving from left to right, the electronegativity increases due to the increase in effective nuclear charge.
Therefore, we can deduce that
Cl > P > Si (EN) [same period]
Cl > Br (EN) [same group]
Therefore,
Cl has the highest electronegativity,
