Draw acceptable Lewis structures for the molecular ion (radical cation) formed fromthe following molecules when each is bombarded by high-energy electrons in a massspectrometer.
Chapter 5 Lecture Notes CHEM 1030 Rik Blumenthal Ionic Compounds and Ionic Bonding o Ionic compounds form when cations (atoms with positive charge) and anions (atoms with negative charge) combine. Ex. NaCl Na (sodium) is a cation Cl (chlorine) is an anion When combined, the single electron from sodium completely transfers to chlorine, a process called ionization o Ionic compounds denoted in chemical formulas (show elements in ration in which they combine) Ex. Li + O L2 O Notice that Li has one valence electron and O has two valence electrons. SO To be electrically neutral, Li must appear in two. o The structural arrangement of ionic compounds are appear in a lattice structure Ionization, the addition of electrons to an atom, requires energy. That energy is called lattice energy (amount of energy required to convert a mole of an ionic solid to the gas phase). o Lattice energy is a measure of a compound’s stability Lattice energy increases with electronegativity Stability increases with electronegativity Higher Lattice Energy = More Stable Compound Naming Ions a
