Reply: sigma-bond is stronger. It is because sigma-bond is shaped by head-on overlapping of atomic orbitals and Π bond is fashioned by aspect intelligent overlapping.
as the addition of one or more electrons would bring about increased repulsion One of the electrons along with a decrease in efficient nuclear cost.
CISCE board has an international typical of your instructional setting. They follow Cambridge University to control international education and learning in India According to the nations’ needs.

Sometimes, like in noble gas, atoms don't have any attraction to achieve an electron. In that case Strength should be supplied.
Atomic sizing. As the dimensions of the atom boosts, the space amongst its nucleus plus the incoming electron CBSE Class 11 Biology also boosts. Therefore, the drive of attraction between the nucleus plus the incoming electron decreases and hence the electron gain enthalpy gets less damaging.
The higher steadiness of the entirely filled noble fuel configuration causes quite large second ionisation enthalpy for sodium. Alternatively, Ma+ formed after losing very first electron nevertheless has another electron in its outermost (3s) orbital. Due to this fact, the second ionisation enthalpy of magnesium is way scaled-down than that of sodium.
