Question

Ionisation energy and electron gain enthalpy of H-atom have sign

IE= +Ve; EGE = +Ve
IE = -Ve; EGE = -Ve
IE = +Ve; EGE = - Ve
IE = - Ve; EGE = +Ve

Answer 1

Answer:

IE = +ve, EGE = -ve.

Explanation:

Thus we need to provide energy to ionize hydrogen and hygrogen acquires electeon with the release of energy.

Answer 2

Ionisation energy and electron gain enthalpy of H-atom have sign is IE = +ve, EGE = -ve.

Explanation:

1.Thus we need to provide energy to ionize hydrogen and hygrogen acquires electeon with the release of energy.

2.Energy is released when an electron is added to the atom. Therefore, the electron gain enthalpy is negative.

3.The electron gain enthalpy for halogens is highly negative because they can acquire the nearest stable noble gas configuration by accepting an extra electron.

4.Ionization energy, also called ionization potential, in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule.

5.Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom. During the addition of an electron, energy can either be released or absorbed.
