FIRST OF ALL WE SHOULD KNOW THE ELECTRONIC CONFIGURATION OF THESE TWO

●●●●●●●●●●●●●●●●●●●●●

ELECTRONIC CONFIGURATION OF Be ( BERYLLIUM ) is :-

●●●●●●●●●●●●●●●●●●●●●

1s^2 ,2s^2

●●●●●●●●●●●●●●●●●●●●●

ELECTRONIC CONFIGURATION OF B ( BORON ) IS :-

●●●●●●●●●●●●●●●●●●●●●

1s^2 , 2s^2

●●●●●●●●●●●●●●●●●●●●●

WE KNOW THAT PARTIALLY AND FULL FILLED ORBITALS ARE MORE STABLE AND REMOVING ELECTRON FROM THESE BECOME DIFFICULT .

●●●●●●●●●●●●●●●●●●●●●

SO BERYLLIUM HAS FULL FILLED ORBITAL DUE TO WHICH IT IS STABLE AND ITS DIFFICULT TO REMOVE AN ELECTRON FROM IT AS COMPARED TO BORON WHICH HAS HALF FILLED ORBITAL WHICH IS LESS STABLE THEN FULL FILLED , SO FIRST WE HAVE TO REMOVE AN ELECTRON FROM BORON TO MAKE IT MORE STABLE.

THIS IS THE REASON DUE TO WHICH BERYLLIUM HAS GREATER ELECTRONEGATIVITY THAN BORON
