Yes you are correct. At 1:48 I did mean electrons. Nice catch and thank you for your comment.

see screencast at 7:32.

HF bond is Ionic due to large electronegativity difference.

Thinking of it in another way, the one H valence electron can't wait to jump in and fill the "hole" in the 7 of 8 valence electrons needed to complete the desired octet for F.

Therefore: Ionic--electron transfer Covalent--electron sharing

The above represents initial chemistry knowledge, the actual behavior of electrons can be studied further in more advanced chemistry courses.

At 1:48 you say 'that's six orbitals' when referring to P orbitals - I believe you meant electrons.

sir, H and F bond is what kind of bond??

ionic or polar covalent??
