Account for the following:
Noble gases have large positive electron gain enthalpies.

Account for the following: Noble gases have very low boiling points.

Choose the incorrect statement. : Chemical reactivity tends to be high in group 1 metals, lower in elements in middle and increases to maximum in the group 17., Halogens have very high negative electron gain enthalpy., Noble gases have large positive electron gain enthalpy., Decrease in electronegativities across a period is accompanied by an increase in non-metallic properties.

Justify the following: 'Ne' has positive value for electron gain enthalpy.

Which of the following has largest negative electron gain enthalpy?

Second electron gain enthalpy Is ͟ ͟ ͟͟͟

Assign reason for the following:- The negative Value of electron gain enthalpy of fluorine is less than that of CI.

Assertion : Noble gases have positive electron gain enthalpy. Reason : Noble gases have stable closed shell electronic configuration.

Which of the following will have the most negative electron gain enthalpy and which the least negative ? P,S,Cl,F. Explain your answer.
