Term
molecular orbitals
 Definition
when atomic orbitals overlap
Term
sigma bond
 Definition
2 atomic orbitals combine to form a molec. orbital that is symmetrical along the axis connecting the 2 atomic nuclei
Term
what does vsepr say
 Definition
states bc electrons repel, molecular shapes adjusts so VE pairs are as far apart as possible
