- Write the Lewis symbols for each of the following ions: (a) As3 (b) I (c) Be2+ (d) O2 (e) Ga3+ (f) Li+ (g) N3arrow_forwardDefine 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_forward(1) What is the total number of valence electrons in the Lewis structure of SF2? electrons (2) Draw a Lewis structure for SF2arrow_forward
- What is the difference between a Lewis dot symbol and a Lewis structure?arrow_forward10.) The structural formula of a certain aldehyde (related to formaldehyde) is H3C-CH2-CHO. Draw a Lewis structure for this aldehyde and determine the number of bonds present. Note that a single or a double or a triple bond counts as one bond. Write the number, not the word.arrow_forwardDraw the Lewis structures for each of the following ions or molecules. Give the number of electrons in each species. Remember to enclose ion s in square brackets with the charge as a superscript outside the right bracket. (a) SO 2 (b) XeO 2 F 2 (Xe is the central atom) (c) ClF 3 (d) ClO 2 F (Cl is the central atom) (e) BrO 4 -arrow_forward
- Consider the following compounds: BeCl 2 , MgBr 2 , and SrBr 2 . Answer the following questions based on expected periodic trends: (a) Which is expected to have the shortest ionic bonds? (b) Which is expected to have the highest lattice energy? (c) Which is expected to have the lowest melting point?arrow_forward#6. Consider the Lewis structure below where X is an element from the third period (Na-Ar). (a) Identify the central atom, X, when n = - -1. (b) Determine the formal charge on X. (c) Draw a Lewis structure so that the formal charge on X is equal to +1. :Ö: [+] n-arrow_forwardConsider the Lewis Structure for the molecule, [BrCl4]. On your own, make a sketch of the VSEPR shape, and use that to answer the following questions: :Cl: :Cl,Br- -Br÷Cl:arrow_forward
- where is c? in the lewis structure?arrow_forwardDraw the Lewis structure for the polyatomic trisulfide ($3-) anion. Be sure to include all resonance structures that satisfy the octet rule.

(a) A covalent bond is formed between two atoms whose difference in electronegativity is less than 1.9. (b) If the difference in electronegativity between two atoms is zero (they have identical electronegativities), then the two atoms will not form a covalent bond. (c) A covalent bond formed by sharing two electrons is called a double bond. (d) In the hydrogen molecule (H2), the shared pair of electrons completes the valence shell of each hydrogen. (e) In the molecule CH4, each hydrogen has an electron configuration like that of helium, and carbon has an electron configuration like that of neon. (f) In a polar covalent bond, the more electronegative atom has a partial negative charge (8–) and the less electronegative atom has a partial positive charge (&+). (g) These bonds are arranged in order of increasing polarity C–Harrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
