Expert Solution

Answer to Problem 8.1VP

Solution

The group that corresponds to the elements with one valence electron in the periodic table is group 1 .

Explanation of Solution

Explanation

The number of period signifies for the number of valence electrons f the element in the periodic table.

The elements are arranged in the order of increasing atomic number. Therefore, as the atomic number proceeds, the electrons are filled in the valence shell of the element. The filling of the electrons are repeated once the valence electrons are completely filled.

With this pattern of filling of electrons, the elements are placed in the group as,

Group 1 elements contain one valence electron.
Group 2 elements contain two valence electrons.

A small artisanal cheesemaker is testing the acidity of their milk before it coagulates. During fermentation, bacteria produce lactic acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and develop flavor. The cheesemaker has measured that the developing mixture contains lactic acid at an initial concentration of 0.025 M. Your task is to calculate the pH of this mixture and determine whether it meets the required acidity for proper cheese development. To achieve the best flavor, texture and reduce/control microbial growth, the pH range needs to be between pH 4.6 and 5.0. Assumptions: Lactic acid is a monoprotic acid H H :0:0: H-C-C H :0: O-H Figure 1: Lewis Structure for Lactic Acid For simplicity, you can use the generic formula HA to represent the acid You can assume lactic acid dissociation is in water as milk is mostly water.

Explanation

The number of period signifies for the number of valence electrons f the element in the periodic table.

The elements are arranged in the order of increasing atomic number. Therefore, as the atomic number proceeds, the electrons are filled in the valence shell of the element. The filling of the electrons are repeated once the valence electrons are completely filled.

With this pattern of filling of electrons, the elements are placed in the group as,

Group 1 elements contain one valence electron.
Group 2 elements contain two valence electrons.
Group 13 elements contain three valence electrons.
Group 14 elements contain four valence electrons.
Group 15 elements contain five valence electrons.
Group 16 elements contain six valence electrons.
Group 17 elements contain seven valence electrons.
Group 18 elements contain eight valence electrons.

Therefore, the elements of group 16 contain six valence electrons.

Conclusion

a. The group that corresponds to the elements with one valence electron in the periodic table is group 1 .
b. The group that corresponds to the elements with four valence electrons in the periodic table is group 14 .
c. The number of period signifies for the number of valence electrons f the element in the periodic table.
