- 2.42 What is a period in the periodic table? From what does it derive its name?arrow_forwardHow do binary compounds with hydrogen illustrate the concept of periodicity?arrow_forwardDoes the information on alkali metals in Table 2-8 of the text confirm the general periodic trends in ionization energy and atomic radius? Explain.arrow_forward
- In each of the following sets of elements, which element would he expected to have the highest ionization energy? msp;a.Cs,K,Lic.l,Br,Clb.Ba,Sr,Cad.Mg,Si,Sarrow_forward2.84 Early attempts to arrange the elements often focused on atomic weight. Mendeleev considered a number of properties in addition to atomic weight, so he realized that some elements seemed out of place when ordered by atomic weight. Using the modern periodic table, identify elements for which Mendeleev must have had to switch the order in order to get the correct sequence of elements.arrow_forwardQuestion:Consider two elements, Element A and Element B, from the periodic table. Element A is located in Group 1 and Period 3, while Element B is located in Group 16 and Period 2. (a) Which element would have a larger atomic radius, Element A or Element B? Justify your answer. (b) Predict the ionization energy of Element A and Element B. Which element would have a higher ionization energy? Explain your reasoning. (c) Based on their positions in the periodic table, which element would be more likely to form a stable cation? Provide a brief explanation for your choice.arrow_forward

What do their placements in thetable have in common?(c) Find the three elements represented with red dotson a periodic table. What do their placements in thetable have in common?(d) Based on the graph, what is the radius of C?arrow_forwardA neutral atom has two electrons with n = 1, eight electrons with n = 2, eight electrons with n = 3, and two electrons with n = 4. Assuming this element is in its ground state, supply the following information:(a) atomic number(b) total number of s electrons(c) total number of p electrons(d) total number of d electrons(e) Is the element a metal, metalloid, or nonmetal?arrow_forwardWrite full electron configurations for each element.(a) N (b) Mg (c) Ar (d) Searrow_forward
