Heisenberg:- it states that it is impossible to determine simultaneously exact position and momentum of an electron. Aufbau:- electrons are filled in the atomic orbitals in the increasing order of orbital energy. Pauli :- no two electrons in an atom have the same set of four quantum number. Surface tension:- it is the perpendicular force acts on the surface per unit length.

.....in hydrogen and flourine both have nehative charge but flourine is more neative so it will attract the hyroden's elctron and forms a postive charge in it . so this all about hyroden bond . and also hyroden bond is weeker then vander wall . so this is my point of view ....so i summerice it all

Riya Kumari 6 years, 1 month ago

Hydogen bond occur due to difference of polarity mens difference in charges i.e more negitively charge atom attract less negitive electon and a bond forms e.g hydrogen and flourine bond H—f in this

The bond arrises due to the difference between the polarity of two atoms is called hydrogen bond... It is a type of dipole-dipole attraction.... HF,H2O etc.
