1 Answer the following questions as we go through the review Bonding Test ReviewAnswer the following questions as we go through the review
2 covalent ionic anion cation Name for an atom that has gained electronsName for an atom that has lost electronsShared pair of electrons between two atomsInvolves a complete transfer of electrons
3 Magnesium Iodine Krypton Would gain electrons and form a negative ionWould lose electrons and form a positive ionTwo that would combine to form an ionic compoundHas a greater electronegativity
4 0 to to > 1.7Electronegative difference resulting in ionic bondElectronegative difference resulting in nonpolar covalent bondElectronegative difference resulting in polar covalent bond
5 tetrahedral outermost s&p’s 32 resonance structure 2 polar Suborbitals comprising valence electronsA structure that cannot be represented by one modelNumber and type of bonds in a nonpolar molecule of MgH2Number of valence electrons in PO4-3Shape of methane (CH4)
6 Bond energy crystal lattice valence electrons ionic bonds Measure of bond strengthThree dimensional arrangement of positive and negative ionsOutermost s and p electronsBonds formed by electrostatic forces
7 Isoelectronic mobile charged particles electronegativity covalent What nonmetals must have to conduct electricityAttraction for a shared pair of electronsHaving the same number of electronsFormed by sharing electrons
8 VSEPR theory double covalent triple covalent polyatomic ion Sharing of 4 electronsSharing of 6 electronsElectrons orient themselves to minimize repulsive forcesIndividual atoms bonded by covalent bonds
9 Two points that determine a polar molecule Do resonance structures violate octet rule?Is a molecule with dipole moments in opposite directions polar?Can a molecule have both ionic and covalent bonds?
10 Opposite directions repulsive forces three-dimensional lone pairs Electron dot structures are oftenArrangement of atoms in molecules depends on the arrangement of bonding and __________ of electrons.Attractive forces must be greater than ___ before a covalent bond can formWater is polar because the two dipoles do not point in __________.
11 Attraction for a shared pair of electrons Formed by sharing electrons Isoelectronic mobile charged particles electronegativity covalent VSEPR theoryAttraction for a shared pair of electronsFormed by sharing electronsElectrons orient themselves to minimize repulsive forcesHaving the same number of electronsWhat nonmetals must have to conduct electricity
12 Like dissolves like: polars combine with polars, nonpolars with nonpolars: polar molecules do not combine with nonpolar moleculesWhich elements will form positive cations when they react?sodium, sulfur, chlorine, calcium, fluorineWhich elements will form negative anions when they react?The arrangement of atoms in a molecule depends on the arrangement of bonding and lone pairs of electrons.For polar molecules to form the atoms must be connected by polar bonds and have a non-symmetrical shapeCations combined with a polyatomic ion form a compound having both ionic and covalent bondsThe greater the difference in electronegativity of a metal and a nonmetal the higher the melting point of the ionic compoundHow many valence electrons in PO3-3Why are noble gases not normally found in compounds?
