QUESTION 1 Reactivities pattern of metals in the periodic table Reactivity of metals in general increases from right to left and from top to bottom on the periodic table. Chemical reactions are in essence electron interactions among the atoms involved in the reactions. Thus, the likeliness of valence electrons being detached from the atom of a metal increases the reactivity of the atom. 12pt 4 points Explain why there exists such reactivity pattern of the metals in the periodic table as described above. (You may use specific metals as examples for your explanation.) Tip: think about easiness of achieving octet rule by removing electrons among metals.

QUESTION 2 The following are examples of reactivity-patterns of some metals: Metals that react with cold water: Li, K, Na, Ca, etc. Metals that do not react with cold water but with hot steam: Mg, Al, Zn, Cr, etc. Metals that neither react with cold water nor with hot steam, but with acids: Co, Ni, Sn, Pb, etc. Here are the two questions: 1. Match the top and the bottom pictures with the respective elements. 2. What state is the H₂O in each case, i.e., cold water or hot steam? 3 points These reactivity-patterns of the metals listed above are in line with the metal's reactivity-trend described in Question #1 above. For instance, since K is more reactive than Al (again according to the trend described in Question #1), K can easily react even with cold water. However, Al can't react with cold water; Al can only react with hot steam because Al is less reactive than K. You can also draw a similar reasoning if you compare, for instance, Al with Pb. Al can react with hot steam. However, Pb can't react with hot steam; Pb can only react with acids (i.e. only with such chemicals as acids!) because Pb is less reactive than Al. The following two pictures show the reactions of sodium (Na) and magnesium (Mg) with H₂O. The top picture (a) shows a greater (faster) extent of reaction with H₂O than the bottom picture (b).

QUESTION 3 3 points The following pictures show the intensity of reaction of certain metals with an acid. And the intensity increases to the right: the left picture the least reactive, the right picture the most reactive, and the middle picture intermediately reactive. Using the examples of the reactivity patterns of the metals in Question # 2 above, answer the following three questions. 1. What metals could represent the reaction at the left picture (a)? List all possible metals. 2. What metals could represent the reaction at the middle picture (b)? List all possible metals. 3. What metals could represent the reaction at the right picture (c)? List all possible metals. 13 Save Answer
