|---|---|---|---|---|---|
| Octet Rule | needs 8 valence electron to be stable. **atoms that are not noble gases form octets*** no noble gases(have no octet)
🗑
|
||||
| Ionic Bond | Transfer(lose/gain) -> ("Attraction" betw opposite charged ions)
🗑
|
||||
| Covalent Bonds | Sharing
🗑
|
||||
| Ionic Compound( ex. NaCl) | has pos & neg ions, held together by strong attraction between opposite charged ions, high melting point,solids,
🗑
|
||||
| Subscripts | represents the number of positve & negative electron that give overall charge of zero
🗑
|
||||
| Positive charge of ion | equal to group number EX; group 1A= 1+, 2A= 2+
🗑
|
||||
| Ionic Formula | pos & neg ions, neutral,has charge balance(total pos chrg= total neg chrg),symbol metal written first then non metal
🗑
|
||||
| write ionic formula | Ba2+Cl- write symbol w/ions balance charges(2Cls needed) BaCl2
🗑
|
||||
| naming Ionic compounds w/2 elements | Identify cation & anion, cation first, followed by anion w/ide ending.
🗑
|
||||
| 6 form more than 1 type Ion | Cr-Chromium, Fe-Iron, Cu Copper,Au gold,Sn-Tin,Pb-Lead
🗑
|
||||
| Non metal Ions (ionic comp w/2elements) | when non metals are formed into ions, change the end name to "ide"
Ex; NaCl= sodium Chloride
🗑
|
||||
| Metals that form more 1 cation | C**Use roman numeral to name ionic charge*** Chromium Cr, Copper Cu, Iron Fe,Tin Sn,Lead Pb,Gold Au Ex; Copper(II)sulfide=Cu2S
🗑
|
||||
| Polyatomic Ions | group of Atoms, has overall ionic charge, Ex: OH- Hydroxide NO-3= Nitrate
🗑
|
||||
| Covalent Compounds | Electrons are shared,2non metals,groups 14-17, each atom has complete outer shell(octet) or duet(hydrogen)
🗑
|
||||
| Duet | Hydrogen shell
🗑
|
||||
| Hydrogen Molecule | stable w/2electrons(helium),has shared pr of electrons,
🗑
|
||||
| naming covalent compounds | prefixes are used to name atoms
🗑
|
||||
| mono | 1
🗑
|
||||
| Di | 2.....
🗑
|
||||
| Tri | 3.....
🗑
|
||||
| Tetra | 4......
🗑
|

| octa | 8....
🗑
|
||||
| nona | 9....
🗑
|
||||
| deca | 10
🗑
|
||||
| Electronegativity | attraction for an atom of shared electron *increase left to right gng across period on periodic table,high nonmetals, Fuorine highest, low for metals
🗑
|
||||
| Non Polar Covalent Bonds | *(0.0-0.4)**between non metals,unequal sharing electrons,no electronegativity
🗑
|
||||
| Polar Covalent Bond | ***(0.5-1.7)****non metal,unequal share electrons
🗑
|
||||
| Properties of Ionic Bonds | ****(1.8-higher)**** between metal & nonmetals, electron transfer
🗑
|
||||
| Tetrahedral shape | 4 bonds
🗑
|
||||
| Prymadial | 3 bonds
🗑
|
||||
| bent shape | 2 bonds
🗑
|
||||
| VSPER | VALENCE SHARE ELECTRON PAIR REPULSION THEORY arranged apart,least amt repulsion
🗑
|
||||
| Polar molecules | has polar bonds,has separation w/pos & neg charge w/dipole
🗑
|
||||
| NonPolar Molecules | contain non polar bonds or has symetrical arrangement( bonds that are identical) O=C=O H-H
🗑
|
||||
| Dipole Dipole attractions | covalent & polar molecules, form strong bonds, F,O,N very electronegativity
🗑
|
||||
| Dispersion forces | weak attractions between non polar molecules,temp dipoles develop w/electrons arent distributed equally
🗑
|
||||
| strongest/Hydrogen | Ionic, Hydrogen are stronger than dipoles
🗑
|
||||
| Dipoles | separation of positive & neg charges in polar bonds indicated by an arrow from more pos to neg atom
🗑
|
||||
| Dipole in polar covalent bond | subtract number, higher number - sign lower number + sign
🗑
