Unit 7-8 Vocab 1. Chemical bonding - Forces that hold groups of atoms to make them function as a unit 2. Ionic Bonding -electrons are transferred 3. Covalent Bonding -electrons are shared equally by nuclei 4. Polar Covalent -Unequal sharing of electrons between atoms in a molecule 5. Electronegativity -a measure of the tendency of an atom to attract a bonding pair of electrons 6. Bond Polarity- the sharing of electrons between atoms. 7. Dipole Moments- differences in electronegativity. 8. Isoelectronic- a series of ions/atoms containing the same number of electrons 9. Lattice Energy- How strongly the ions attract each other in the solid state 10.Ionic compounds- any compound that conducts an electric current when melted 11.Octet Rule- elements form table molecule’s when surrounded by eight electrons 12.Lewis Structure- shows how valance electrons are arranged among atoms in a molecule 13.Resonance- describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
