The element having highest electron affinity is
Chlorine has the highest electron gain enthalpy among these because electron gain enthalpy decreases on moving down a group. Fluorine has less electron gain enthalpy due to its small size.
Which of the following has the highest second ionisation energy?
The electronic configuration of the element with maximum electron affinity is
The first ionisation energy of oxygen is less than that of nitrogen. Which of the following is the correct reason for this observation?
The charge/size ratio of a cation determines its polarizing power. Which one of the following sequences represents the increasing order of the polarizing power of the cationic species, K+, Ca2+, Mg2+, Be2+?
Which one of the following arrangements represents the correct order of electron gain enthalpy (with negative sign) of the given atomic species?
