Making sense of molecular orbitals using Orca, Avogadro and Chemcraft (exemplified with Methane)

[@cellotron4758]

Hey there! I'm currently an IB student doing their chem IA, and I was wondering about something that I'm having a lot of trouble finding simple explanations for. When I draw a ethenenitrile molecule and see the partial charge of the nitrogen atom on avogadro, and an ethanal molecule and see the partial charge of the oxygen atom on avogadro, the oxygen has a lower partial charge than nitrogen.
When comparing this change of the leftmost (or rightmost) atom from nitrogen to oxygen, I would expect the partial charge to increase because the electronegativity of oxygen is higher than the electronegativity of nitrogen. Do you know why this could be the case?
Also, do you potentially know how partial charges would affect the bond angles in molecules (this is actually what my IA, Internal Assessment, is about)?

Thanks for your video. could you suggest me how to turn the black background into white in Avogadro. thanks again. your voice seems to me like a drunk person. sorry!!
