Do higher electronegativity atoms tend to draw more electrons to them?

And thus making their formal charge negative?

Yes because electronegativity describes the tendency of an atom to attract a pair of electrons making it more negative.

Typically yes the formal charge would become negative. But in CO, the carbon has a negative 1 charge and oxygen has a positive 1 charge. You would think that this should be swapped but you first must satisfy the octet before trying to move or change formal charges. In some cases the more electronegative atom cannot have the plus 1 charge in order to complete the octet. But yes, the higher the electronegativity of the atom, the greater likelihood of it attracting electrons.

Yes, higher electronegative atoms tend to draw more electrons to them because the higher the electronegativity, the greater tendency the atom is to attract electrons. This is why electronegativity increases from left to right, and the higher it is on the periodic table (these atoms are usually closer to an octet, thus wanting to gain an electron, which makes their formal charge negative).

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Therefore a small electronegativity difference leads to a polar covalent bond and large electronegativity difference leads to an ionic bond.

Yes, as you know anions will have a negative charge which pulls more electrons. And electronegativity is the electron’s affinity. Therefore, the more electronegativity the more electrons are pulled.

Higher electronegativity atoms do tend to draw more electrons towards them as electronegativity is a measure of an atoms tendancy to attract electrons. As an example, Oxygen has a very high electronegativity and often has a negative formal charge due to its attraction of electrons.
