Al Cl Si What is the electronic geometry about a central atom which has the following number of regions of electron density? 2. a) Four regions of electron density: b) Six regions of electron density: Define dipole moment. Distinguish between polar and nonpolar bonds. Give an example of each. 3. 4. Draw Lewis structures for BF, and NF. Compare the geometries, bond angles, and polarities. Give the electron pair geometry and the molecular geometry of BF, and NF, according to VSEPR. 5. Draw the three resonance structures of the CO, molecule.

Answer 1

please do summit differnt question speratly we suppose to do anwer of only one questio thank you

(1) Lewis dot structures Al - > Al: Cl - > cl: K^+ - > k^+ O^2 - - > O: Si - > Si: in levis dot structure we show the valence electron of a atom or ion.
