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.
Group 13 elements contain three valence electrons.
Group 14 elements contain four valence electrons.
Group 15 elements contain five valence electrons.
