What is the maximum bond order that is possible between elements in the first two rows of the periodic table

3

What is the bonding order?

Bonding/ nonbinding (1/2)

What is impossible for bond order values

Negatives it CAN be fractions but not negative

Bond order allows us to identify what?

The net number of electron pairs participating in bonding interactions

According to MO theory an electron contributes to a bonding interaction if it occupies a

bonding orbital

The energies of the molecular orbitals for homo nuclear diatomic molecules from the second period will decrease as

Effective nuclear charge increases

A molecular orbital is

A wavefunction occupied by a single electron in a molecule

When out of phase atomic orbitals combine they create

Antibonding molecular orbitals

What is linear combination of atomic orbitals

The process of combining atomic orbitals to generate molecular orbitals

Percent composition formula

%= gram what you want / gram sample (100)

molecules that have the same number of the same types of atoms connected in the same way have the same

Structural, molecular, and empirical formula

What formula tells you the most about a compound

The structural formula

A carbon atom that displays linear geometry is likely to be participating in what kind of bonds

One triple bond and one single bond

A “node” is a characteristic in which of the following

Pi bond because the orbitals overlap parallel to the inter nuclear axis so along the axis itself a node forms
