Step by step
Solved in 2 steps
- What is the net charge on the following tripeptides (single-letter abbreviations). * YLV at pH 10.9 (the answer is -1.5 but I don't understand why)Exactly what causes the charges to form on atoms in ionic bonds?In which of the following pairs is the first element expected to have a higher electronegativity than the second? (1 Point) O O, P O Cs, Rb O I, Br Al, P
- What are nonpolar bonds?Discuss whether the following statement is correct: “An ionic bond can, in principle, be thought of as a very polar covalent bond. Polar covalent bonds, then, fall somewhere between ionic bonds at one end of the spectrum and nonpolar covalent bonds at the other end.”When two atoms share a pair of valence electrons with different levels of electronegativity, what type of bond is this?
- How many electrons are in the outer shell of each of the following atoms?Look up the valence electron configuration, covalent atomic radius, effective nuclear charge, first ionization energy and Pauling electronegativity in Chapter 8 (tables are attached). Examine the above data and answer the following questions. a) Explain why some of the elements like TI and Pb on the lower left of the p block are metallic. b) Explain why some of the elements like C, Si in the center of the p block form covalent bonds. Explain why these bonds formed by the network of these elements (as studied in Chapter 25) tend to be unreactive. c) Explain why the noble Group 8A elements are highly unreactive gases. d) Explain why some elements like F, CI, Br etc, on the upper right of the p block are highly reactive nonmetals.Which among the four bonds is strongest? And which one is weakess? Explain.

Taking into account that: Non-polar covalent: greater than or equal to 0 but less than 0.7 Polar covalent: greater than or equal to 0.7 but less than 1.7 ionic: greater than 1.7 A)NO B)KCI C)F2 C)AsOIdentify the chirality center (sometimes called chiral atom) in each molecule. If the molecule does not contain a chirality center, select nonewhat determines if a bond is polar?
