Homework Answers
Part 1. Metallic groups or elements show the electropositive character, i.e. they have the tendency to lose the electrons, whereas the nonmetallic groups or elements exhibit the electronegative character, i.e. they have the tendency to gain the electrons.
Part 2. The metal groups are the S-block elements: IA group elements (alkali metals) - Li, Na, K, Rb, Cs; IIA group elements (alkaline earth metals) - Be, Mg, Ca, Sr, Ba; P-block elements: IIIA group elements - Al, Ga, In, Tl; IVA group elements - Sn, Pb; VA group elements - Sb, Bi; VIA group elements - Po
The nonmetal groups are the P-block elements: III A group elements - B, IVA group elements - C; VA group elements - N, P; VIA group elements - O, S, Se; VIIA group elements - F, Cl, Br, I

Atomic radius Nbonding The radius of an atom describes the distance between the nucleus and the outermost electron. This distance is very small so it is often reported in picometers (101 m) or angstroms (10-10 m). One way of measuring the atomic radius is to observe the distanc between bonding atoms. The distance between the nuclei of the bonding atoms is equal...

Please help 1. The most chemically reactive metal elements are soft. These metals are so reactive that they react spontaneously with water and/or substances in the atmosphere and therefore must be stored under oil. Where is this family (group) of metals located in the periodic table? 2. Based on for Li, Na and K and the relationship between reactivity and positions of elements in the periodic table, what would you predict for the reactivity of Rb? 3. Looking at the...

Can somebody please explain the difference between the catalytic triads of trypsin and chemotrypsin? I know that chemotrypsin is a Ser protease while trypsin is an Asp protease but what does that mean more specifically. I tried looking up structures for both of the triads and found that they both contain Ser195, His57 and Asp102 and they are connected in the same manner too. I am really confused between the differences, please help. Thank you

I really appreciate if someone can tell me how I can know the major and minor species for the tritations of strong base- strong acid, strong acid- strong base and weak acid- strong base. I am looking for the major and minor species at the point before any addition of titrant, before the equivalence point, at equivalece point and after equivalence point. Could you please give a detailed explanation with the chemical equations. Thanks

Please explain in detail. Thanks!!
Remember, you're looking for the less substituted group, so "b" is correct.... 1) ВН, 2) Н,О, ОН- 3) Н,О b a CH3 CH3 он н н он less substituted, anti-markovnikov
