ELECTRONEGATIVITY Electronegativity is: The ability of an atom to attract electrons to itself Atomic Rizz... LMAO? LOOK HERE ↓ Increasing electronegativity 1A H 2.2 2A Be 3A 4A 5A 6A/7A Li BCNOF 1.0 Na 1.6 SP 1.8 25 30 34 40 Mg SC 0.9 1.3 1.9 2.2 26 3.2 K Br 0.8 3.0 2.7 According to this image electronegativity increase as we go to the left and up the periodic table. Fluorine is the most electronegative Let's look at the Bohr Diagram to figure out why Fluorine is the most electronegative F needs one more e to have a full octet. So if he finds an atom willing to give him an e, he will have a full outer shell and become stable. N10 How do we notate? 8 This is small delta St partial positive (less e- density) Increasing electronegativity δ This is small delta δ+ partial positive (less e- density) δ- partial negative (more e- density) Example: what's more electronegative? 5+ H-C These are values 6 I got from the diagram 2.2 2.5 HYBRIDIZATION Firstly: Orbitals: region in space where the probability of finding an e- is high. max # e-s per orbital is 2 ↑↓ one spins and the other spins down Atomic orbitals H-C-H 2 H Hybridized orbitals Hybrid atomic orbitals: One "s" and 3"p"
