Concept introduction:
The Lewis dot symbols contain dots, which give information about valence electrons.
The Lewis dot symbols represent both bonds and lone pairs as dots.
The Lewis structures represent bonds as lines and lone pairs as dots.
Octet rule states that an atom can only have eight electrons in its outermost shell.
For many molecules, it is impossible to explain all their properties by a single Lewis structure. In such cases, more than one Lewis structures are drawn to explain the properties. Such structures of a compound are called resonating structures and this phenomenon is called resonance.
Due to attraction toward electrons, the ions and the molecules get some charge over them, which is called the formal charge.
Formal charge can be calculated as
Total number of valence electrons in a free

- Define the term lattice energy. Why, energetically, do ionic compounds form? Fig. 3-8 illustrates the energy changes involved in the formation of MgO(s) and NaF(s). Why is the lattice energy of MgO(s) so different from that of NaF(s)? The magnesium oxide is composed of Mg2+ and O2 ions. Energetically, why does Mg2+O2 form and not Mg+O? Why doesnt Mg3+O3 form?arrow_forwardA polyatomic ion is composed of C, N, and an unknown element X. The skeletal Lewis structure of this polyatomic ion is [XCN]. The ion X2 has an electron configuration of [Ar]4s23d104p6. What is element X?

(a) Cl2CO (b) H3C—CN (c) H2C—CH2arrow_forward7) which elements from the list below has the following Lewis structure B F N S Si arrow_forwardWhat possible error(s) exist in the Lewis structure (assume we are trying to represent the best possible Lewis structure for the NO₂S ion knowing N is the central atom in this polyatomic ion)? [:ö==S: N= CO :O: The best structure would have double bond and two lone pairs on each oxygen atom and a single bond with three lone pairs on the sulfur. There are no errors. This is the best possible structure. The Lewis structure above does not minimize formal charges, thus is the not the best possible structure. The nitrogen atom has an expanded octet, and this structure is impossible. The Lewis structure contains the wrong number of electrons, thus this structure is impossible.arrow_forward
