Assalamulaikum sir, Sir you said that atomic size increases from group VA to VIIIA so, london despersion force decreses that's why melting and boiling point decrease. But my question is that: Your statement contradict according to group VIIIA because their size is comparatively much larger then group V, VI, VII due to interelectron repulsion so why not melting and boiling point of VIIA is larger but according to graph of perid three argon has too less melting and boiling point?

Sir group 1A to 4A tk Jo molecules Hain wo polar hai???? Ku ka 5A to 8A tk to non polar hai jis ki wajah se melting and boiling point decrease krta hai????

Sir if down the group melting point and boiling point of noble gas and halogen increase because they are non polar then why not increased in sulphur and phosphorous they are also non polar

Sir salam i have a question if boiling point of aluminum is higher than silicon then why melting point of aluminum is lesser than silicon?
@chemistrybyprof.javediqbal Жыл бұрын
Boiling point depend upon only intermolecular forces but Melting point depend upon two factors intermolecular forces and arrangement of structure
