Question

Increasing oreder of 2nd ionisation enthalpy of Li, Be, C, B?​

Answer 1

Answer:

order of 2nd I.E is Li>B>C>Be

Answer 2

Answer:

C

Explanation:

You should know that ionization enthalpy is the amount of energy required to remove an electron depends on which's harder. ( noble gases have the biggest amount of ionization enthalpy especially He )

increase from left to right - decrease from top to bottom

Li3 , Be4 , C6, B5

group 1, 2, 14, 13

the highest will be on the right side which is C6.
