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
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)
what are the following thingies?! AB4, AB3, AB2, AB3E, AB2E2 tetrahedral, triangular planar, linear, trigonal pyramid, bent
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
What are the strongest intermolecular forces? Hydrogen bonding
what is the most significant/extreme dipole-dipole attraction hydrogen bonding
hydrogen bonding is the attraction between a H-atom (bound to F, O, Cl, or N) and a what? nonbonding pair of electrons
name the two weaker forces of attraction induced dipole and london dispersion forces
What force is between a polar and nonpolar molecule? induced dipole
what are the only forces of attraction between nonpolar molecules or atoms of Noble Gases london dispersion forces
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
the mobile electron sea of metals accounts for what properties? conductivity and malleability
put the following forces of atraction in order from strongest to weakest: polar molecules, oppositely charges ions, nonpolar molecules, metal atoms metal atoms, oppositely charged ions. polar molecules, nonpolar molecules
what attractions between particles are almost always solid metal atoms and ions
What are the three particles referred to with 'attractions between particles' ATOMS, iONS, MOLECULES
