In drawing Lewis structures for covalently bonded molecules, the octet rule is used as a guide (remember that for hydrogen the octet is changed to a duet). Shared electrons count toward the electron total for both atoms in the bond. For example, the Lewis structure for SiH4 looks like this ... 

Write Lewis structures that obey the octet rule (duet rule for H) for each of the following molecules. Carbon Is the central atom In CH4, nitrogen Is the central atom In NH3, and oxygen Is the... 

Write Lewis structures that obey the octet rule (duet rule for H) for each of the following molecules. 

Lewis structures are drawn to represent the arrangement of the valence electrons in a molecule. The rules for drawing Lewis structures are based on the observation that nonmetal atoms tend to achieve noble gas electron configurations by sharing electrons. This leads to a duet rule for hydrogen and to an octet rule for many other atoms. 

In writing Lewis structures for molecules, what is meant by the duet rule To which element does the duet rule apply What do we mean by the octet rule Why is attaining an octet of electrons important for an atom when it forms bonds to other atoms What is a bonding pair of electrons What is a nonbonding (or lone) pair of electrons ... 

Lewis structures describe bonding by the use of valence electron dots. They are drawn so as to give hydrogen an electron duet and the other atoms electron octets (octet rule). Formal charge separation should be minimized but may be enforced by the octet rule. 

Give a rationale for the octet rule and the duet rule for H in terms of orbitals. Give the steps for drawing a Lewis structure for a molecule or ion.
