Octet Rule
Most elements want to obtain 8 valence electrons
Exceptions to the octet rule
H, Li, Be, B, Al
Metallic Bonds
The delocalized electrons in a metal are attracted to the negatively charged metal ions
Occurs in all neutral metal atoms
Two elements that have the same electron configuration
Isoelectronic
Oxidation
Losing Electrons
Why do non-metals gain electrons
Small radii, high ionization energy, high electron affinities, large eff
What does group number equal
Charge of the ion
Why is Si 4- not possible?
Large electron electron repulsions
Why does Si 4+ not form during any chemical reactions
Would require too much energy to remove 4 electrons
Si bonds
Covalent
Carbon exception
Can lose or gain 4 electrons, but prefers covalent bonds
When H+ combines with water
It forms an acidic hydronium ion
Most common charge for transition metals
2+
What kind of reaction is ionic bonds
Redox reaction
What are polyatomic ions
Ions that consist of two or more atoms bonded together with covalent bonds
Electrostatic attraction
The attraction between protons and electrons is known as electrostatic attraction. When they are kept at some finite distance apart
