How HF molecule is formed from H– and F– atoms? Explain with electron dot structure.
HF molecule is formed from H and F atoms by the sharing of electrons between the two atoms. In the electron dot structure of HF, the valence shell of H has one electron while the valence shell of F has seven electrons. One electron from the valence shell of H is shared with seven electrons of the valence shell of F to form a covalent bond. The shared electrons are shown by a dash between H and F.
