|---|---|
| what is a stable electron configuration with the s and p orbitals filled | octet |
| what is it called when an atom gains/loses/shares electrons to produce its own octet and become stable? | chemical bonding |
| chemical bonding typically produces a __________, which contains two or more different elements chemically bonded to one another | compound |
| the exception to chemical bonds producing compounds are what two groups? | diatomic elements and metals |
| name the three main forms of bonding and the smallest resulting particle from each type of bond | metallic--atoms, covalent(molecular)--molecules, ionic-- (+)/(-) ions |
| what types of elements are involved in: covalent bonding, metallic bonding, ionic bonding | nonmental/nonmetal; metal/metal; metal/nonmetal |
| what two types of bonding produce compounds? | covalent and ionic |
| _______ give electrons to ________, producing oppositely charged ions that are attracted to eachother in _______ bonding | metals, nonmetals, ionic |
| what gives the simplist ratio of +/- ions in a crystal lattice | formula unit |
| an orderly 3-D arrangement of + and - ions | crystal lattice |
| ionic compounds tend to be _________ _________ with _______ melting and boiling points | brittle solids, high |
| energy released when one mol of the ionic compound is formed | lattice energy |
| what type of bonding involves two or more nonmetals sharing electrons | covalent bonding |
| blending of orbitals of similar energies into orbitals of equal energy | hybridization |
| nonmetals always have what hybridization when forming ONLY sigma bonds | sp3 |
| sp3 hybridization is arranged ____________ with all angles about 109.5 | tetrahedrally |
| a pi bond is attraction between unhybridized ____-orbitals | p |
| t/f VSEPR stands for VALENCE SHELL ELECTRON PAIR REPULSION | TRUE! :) |
| what says that electron pairs surrounding a central atom will separate from eachother by the maximim allowable distance in 3-D shape | VSEPR |
| VSEPR theory is used to predict WHAT?!?! | molecular geometry :) (shape) |

| a triple bond consists of WhAt?! | one SiGMA and two Pi bonds |
| multiple bonds have _______ bond lengths and ________ bond energies | shorter, greater |
| ability of an atom to attract electrons in a covalent bond | electronegativity |
| nonmetals are (more/less) electronegative because they are trying to (gain/lose) electrons | more, gain |
| what element TRUMPS everybody in EN? | FLOURiNE!!! (F) |
| AfTeR FLOURiNE, who is the next EN GiANT! | OXYGEN! |
| name the 6 important elements in EN order from greatest to least | F, O, N, Cl, C, H |
| energy released in forming ionic attraction is what | lattice energy |
| WHICH has greater lattice energy, smaller or larger ions? | SMALLER |
| what is the energy required to break the covalent bond? | bond energy |
| WHATTTT exists between covalently bonded atoms with DIFFERENT ENs (aaalllmmmooosssttt always ;) | BOND POLARITY of course! |
| the less the difference in EN, the greater the bond polarity(t/f) | FALSEEEE |
| when is an bomded atom NONpolar?! | when: there is even sharing of electrons and even distribution of electrical charge |
| relatively weak forces of attraction between molecules | intermolecular forces of attraction |
| attraction between the positive pole of one molecule and the negative pole of another | dipole-dipole |
| the (more/less) polar the molecule, the greater the dipole-dipole attraction | more |

| when do london forces become significant? | at low temperatures or in Large (ORGANiC) moleules |
| London forces create an instantaneous dipole due to what? | random motion of electrons |
| What is a strong attraction between metal cations and a mutually shared 'sea of electrons' | METALLiC BONDiNG |
| t/f metals only have weak attractions for their valence electrons, so valence electrons tend to drift between atoms | TRUE |
