The octet rule first row p-block elements

An atom obeys the octet rule when it gains, loses or shares electrons to give an outer shell containing eight electrons (an octet) with a configuration nf np.  [Pg.41]

Ions such as Na+ 2 2p Mg + (2s /), F (25 2/), CF (3s 3p ) and 0 (2s 2/ ) do in fact obey the octet rule, and they typically exist in environments in which electrostatic interaction energies compensate for the energies needed to form the ions from atoms (see Chapter 6). In general, the octet rule is most usefully applied in covalently bonded compounds involving p-block elements. [Pg.42]

In these examples, only bonding electrons contribute to the octet of electrons. Lone pairs of electrons may also contribute as illustrated in H2O (2.17) and HF (2.18). [Pg.42]

Show that each atom in each of the following molecules obeys the octet rule NF3, CF4, OF2, F2. Draw Lewis structures for the molecules and confirm that the bond order of each bond is one. [Pg.42]

Show that each atom in the [BF4] ion obeys the octet rule. [Pg.42]
