Re: Test 2

Re: Polar Molecules

Although molecules can have polar covalent bonds, there are a few exceptions where the dipole moments cancel each other out; thus, creating non-polar molecules that have polar bonds. Ex: CO 2 and CCl 4 While both C=O and C-Cl bonds are polar, the dipole moments cancel each other out due to their li...

Re: Electronegativity

Can someone explain how shielding works? I understand the concept as when there are more expanded shells of electrons the electrons are further away and the ones in the furthest shell are not pulled on as much, but is it the idea that the ones closer to the nucleus are "stealing" more of ...

Re: Electronegativity

It decreases as you go down the group because the attraction to the nucleus decreases so there is not as much of a pull as higher up.

Only elements from period 3 and beyond can have expanded octets as they can fill up the empty d orbitals that follow higher in energy.

Originally it was Boron Triflouride, BF3, but that only had 6 valence electrons. By adding another Flouride, B completes it octet to form tetraflouroborate anion BF4-,...
