Despite lower value of its electron enthalpy with negative sign,

Chlorine has the highest value of electron gain enthalpy

Ionization enthalpy is the energy required to remove an electron from an isolated gaseous atom in its ground state. Although the atoms are widely separated in the gaseous state, there...

[Hint : Due to smaller size of oxygen than sulphur electron-electron repulsion is more in oxygen than sulphur.]

[Hint : Due to small size of F atom and compact 2p orbitals there are strong interelectronic repulsions in the relatively smaller 2p orbitals of fluorine. So the incoming electron...

Reasons for growth of handloom production are : (i) Adopting technological changes by the weavers to increase production without raising the costs. (ii) Those who catered to the rich always had a...

In our country, women still lag much behind men despite some improvements since Independence. Women face disadvantage, discrimination and oppression in various ways : (i) The literacy rate among women is...

(b) : E°Mn2+/Mn = – 1.18V E°Cr2+/Cr = – 0.91V E°Fe2+/Fe = – 0.44V E°Co2+/Co = – 0.28V

(c) The electron gain enthalpy order for halogens is Cl > F > Br > I Due to small size of fluorine the extra electron to be added feels more...

(d) Electron gain enthalpy for noble gases is positive and it becomes less positive with increase in size of atom.  Value of electron gain enthalpy  He – 48 kJ mol–1, Ne –...

(i) This is due to smaller size of oxygen the electron cloud is distributed over a small region of space, making electron density high which repels the incoming electrons. (ii) Because...
