Which of the following is the name given to the pairs of valence electrons that do not participate in bonding in diatomic oxygen molecules?
The mixing of several atomic orbitals to form the same number of equivalent hybrid orbitals
two or more valid electron dot formulas that can be written for the same molecule
a chemical formula that shows the arrangement of atoms in molecules and polyatomic ions
Because electron pairs repel, molecules adjust their shapes so that the valence-electron pairs are as far apart as possible.
a molecule in which one end is slightly negative and the other end is slightly positive
a covalent bond formed between two diferent atoms in which the bonding electrons are shared unequally
polar covalent bond
When two atomic orbitals combine to form a molecular orbital that is symmetrical along the axis connecting the two atomic nuclei, the bond that is produced is referred to as a/an
In a methane (CH4) molecule, the mixing of one 2s orbital with three 2p orbitals forms
