Correct order of electron affinity of b c n be is
Answers
Explanation:
in decreasing order it will be= N>C>B
Correct order of electron affinity is C > N > B > Be
Explanation:
When an electron is added to a neutral atom to convert it into a negative ion then the amount of change taking place in its energy is known as electron affinity.
Smaller is the size of an atom more readily an electron will be gained by it because of strong force of attraction exerted by its nucleus towards the electron.
So, on moving across a period, there will occur a increase in electron affinity of the atoms as size of atoms decreases from left to right in a periodic table.
As elements of group 15 are half filled so, they are more stable in nature and have slightly less electron affinity as compared to group 14 elements.
Thus the correct order of electron affinity is C > N > B > Be
