Question

Choose the correct order about the electronegativity for the following elements:

• A. $P>Si$
• B. $C>N$
• C. $C>Br$
• D. $Sr>Ca$

Answer 1

The correct option is A $P>Si$

Electronegativity generally increases across a period from left to right and decrease down a group in the periodic table.
As $P$ and $Si$ belong to same period and $P$ is present in group $15$ and $Si$ in group $14$ of periodic table. Hence, eletronegativity of $P>Si$.
