The indicated element should be identified. Also, the atomic number and its group name should be determined. Concept introduction: Periodic table represents a systematic arrangement according to element’s physical as well as chemical properties. Here, elements are represented as a two-letter symbol and are arranged in increasing order of atomic number. Periodic table contains 18 groups (columns) and 7 periods (rows). In periodic table, groups from 1-2 and 13-18 are termed as main group elements. The 10 middle groups from 3-12 are termed as transition elements . There are also 14 elements that started with lanthanum known as lanthanides and 14 elements started with actinium are known as actinides.

Solution Summary: The author explains that periodic table represents a systematic arrangement according to element’s physical as well as chemical properties.
Definition Definition Elements containing partially filled d-subshell in their ground state configuration. Elements in the d-block of the periodic table receive the last or valence electron in the d-orbital. The groups from IIIB to VIIIB and IB to IIB comprise the d-block elements.

Using the graphs could you help me explain the answers. I assumed that both graphs are proportional to the inverse of time, I think. Could you please help me.

Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
