Chapter 2: Problem 42

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{Hg},(\mathbf{b}) \mathrm{At},(\mathbf{c}) \mathrm{Mo},\( (d) \)\mathrm{W},(\mathbf{e}) \mathrm{Sn},(\mathbf{f}) \mathrm{V},(\mathbf{g}) \mathrm{K}$.

Short Answer

Expert verified
(a) Hg, Mercury, atomic number 80, metal. (b) At, Astatine, atomic number 85, metalloid. (c) Mo, Molybdenum, atomic number 42, metal. (d) W, Tungsten, atomic number 74, metal. (e) Sn, Tin, atomic number 50, metal. (f) V, Vanadium, atomic number 23, metal. (g) K, Potassium, atomic number 19, metal.

Step by step solution

01

(a) Identify Hg

Hg, known as Mercury, has an atomic number of 80. It is a metal as it is located in the 'd-block' of the periodic table.
02

(b) Identify At

At, known as Astatine, has an atomic number of 85. It is classified as a metalloid, as it shares qualities of both metals and non-metals.
03

(c) Identify Mo

Mo, known as Molybdenum, has an atomic number of 42. It is a metal, also located in the 'd-block' of the periodic table.
04

(d) Identify W

W, known as Tungsten, has an atomic number of 74. It is a metal, like Mo and Hg, found in the 'd-block' section of the periodic table.
05

(e) Identify Sn

Sn, known as Tin, has an atomic number of 50. It is a metal found in the 'p-block' of the periodic table, specifically in group 14.
06

(f) Identify V

V, known as Vanadium, has an atomic number of 23. It is a metal, as it is also located in the 'd-block' section of the periodic table.
07

(g) Identify K

K, known as Potassium, has an atomic number of 19. It is a metal found in the 's-block' of the periodic table, specifically in group 1 (alkali metals).

A U.S. 1 -cent coin (a penny) has a diameter of \(19 \mathrm{~mm}\) and a thickness of \(1.5 \mathrm{~mm}\). Assume the coin is made of pure copper, whose density and approximate market price are \(8.9 \mathrm{~g} / \mathrm{cm}^{3}\) and \(\$ 2.40\) per pound, respectively. Calculate the value of the copper in the coin, assuming its thickness is uniform.

(a) Which two of the following are isotopes of the same element: ${ }_{46}^{106} \mathrm{X},{ }_{46}^{107} \mathrm{X},{ }_{47}^{107} \mathrm{X} ?(\mathbf{b})$ What is the identity of the element whose isotopes you have selected?
