Ch. 6 Chemical Bonding Review

How does a chemical bond form?

• ALL the electrons are transfered from one atom to another

• valence electrons can be shared or transfered

• the nuclei of each atom are attracted to one another

• the atoms just really like each other

How would you describe a nonpolar molecule?

• the electrons are all shared equally

• the electrons are unevenly shared

• one atom is more electronegative than the others

• one atom hogs the electrons

Elements that bond to themselves, such as Cl₂, O₂, H₂, etc. are examples off...

• polar molecules

• dipole compounds

• diatomic molecules

• asymmetrical molecules
