Question

What is electron gain enthalpy? how does it very along period and group?

Answer 1

Answer:

electron ko gain karte time jo energy change hua called ege

Explanation:

Answer 2

Answer:

Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom.. As we move along the period electron gain enthalpy increases because electrons are added to the same shell. As we go down the group electron gain enthaply decreases because number of shells are adding.
