Chapter 2: Problem 38

Locate each of the following elements in the periodic table; give its name and atomic number, and indicate whether it is a metal, metalloid, or nonmetal: (a) \(\mathrm{Li},(\mathbf{b}) \mathrm{Sc},(\mathrm{c}) \mathrm{Ge},(\mathbf{d}) \mathrm{Yb},\) (e) \(\mathrm{Mn},\) (f) \(\mathrm{Sb},(\mathrm{g})\) Xe.

Short Answer

Expert verified
The elements, their atomic numbers, and their classification are as follows: (a) Lithium (Li) - Atomic number 3 - Metal (b) Scandium (Sc) - Atomic number 21 - Metal (c) Germanium (Ge) - Atomic number 32 - Metalloid (d) Ytterbium (Yb) - Atomic number 70 - Metal (e) Manganese (Mn) - Atomic number 25 - Metal (f) Antimony (Sb) - Atomic number 51 - Metalloid (g) Xenon (Xe) - Atomic number 54 - Nonmetal

Step by step solution

01

(Find Element Names)

Refer to the periodic table and find the full names of each given element: (a) Li - Lithium (b) Sc - Scandium (c) Ge - Germanium (d) Yb - Ytterbium (e) Mn - Manganese (f) Sb - Antimony (g) Xe - Xenon
02

(Find Atomic Numbers)

Now, find the atomic numbers of each element: (a) Lithium - 3 (b) Scandium - 21 (c) Germanium - 32 (d) Ytterbium - 70 (e) Manganese - 25 (f) Antimony - 51 (g) Xenon - 54
03

(Classify Elements)

Determine whether each element is a metal, metalloid, or nonmetal based on their position in the periodic table: (a) Lithium - Metal (b) Scandium - Metal (c) Germanium - Metalloid (d) Ytterbium - Metal (e) Manganese - Metal (f) Antimony - Metalloid (g) Xenon - Nonmetal The elements, their atomic numbers, and their classification are as follows: (a) Lithium (Li) - Atomic number 3 - Metal (b) Scandium (Sc) - Atomic number 21 - Metal (c) Germanium (Ge) - Atomic number 32 - Metalloid (d) Ytterbium (Yb) - Atomic number 70 - Metal (e) Manganese (Mn) - Atomic number 25 - Metal (f) Antimony (Sb) - Atomic number 51 - Metalloid (g) Xenon (Xe) - Atomic number 54 - Nonmetal

(a) What is the mass in amu of a carbon-12 atom? (b) Why is the atomic weight of carbon reported as 12.011 in the table of elements and the periodic table in the front inside cover of this text?

Give the chemical formula for each of the following ionic compounds: (a) sodium phosphate, (b) zinc nitrate, (c) barium bromate, (d) iron(II) perchlorate, (e) cobalt(II) hydrogen carbonate, (f) chromium(III) acetate, (g) potassium dichromate.

In a series of experiments, a chemist prepared three different compounds that contain only iodine and fluorine and determined the mass of each element in each compound: $$ \begin{array}{ccc} \hline \text { Compound } & \text { Mass of lodine (g) } & \text { Mass of Fluorine (g) } \\ \hline 1 & 4.75 & 3.56 \\ 2 & 7.64 & 3.43 \\ 3 & 9.41 & 9.86 \\ \hline \end{array} $$ (a) Calculate the mass of fluorine per gram of iodine in each compound. (b) How do the numbers in part (a) support the atomic theory?

Elements in the same group of the periodic table often form oxyanions with the same general formula. The anions are also named in a similar fashion. Based on these observations, suggest a chemical formula or name, as appropriate, for each of (b) \(\mathrm{SeO}_{3}^{2-}\) the following ions: (a) \(\mathrm{BrO}_{4}^{-}\), (c) arsenate ion, (d) hydrogen tellurate ion.
