CHEM 121 Lecture Notes - Lecture 12: Formal Charge, Hydrogen Fluoride, Covalent Bond
Document Summary
The electron is shared, not transferred completely. They"re then bound together by the electron cloud. Many cases of electron bonding end up in between covalent and ionic. Hydrogen fluoride , hydrogen is very giving and fluoride is very electron hungry , so the electrons are shared unequally. Electronegativity goes up from left to right and bottom to top. (biggest on top, biggest on right: difference bond type, > 0 and < 2 polar covalent, > 2 ionic, 0 covalent. - - - ide. Alkanes: methane (1) , ethane (2) , propane (3) , butane (4) , pentane (5) , hexane, heptane, octane, noname. Know how many carbons is in each of. Nonmetals share enough electrons to complete octet (or duplet; hydrogen) Atoms can share more than one pair to meet the octet (ex. Double bond two atoms share two pairs of electrons. Triple bond two atoms share three pairs of electrons.
