Answer 1

A Period 4 element that is a metal with three valence electrons would be located at Position 13 on the periodic table.

Step-by-step explanation:

In the periodic table, the elements are organized into periods and groups. Periods are the rows that go from left to right, and groups are the columns that go from top to bottom. Each element is represented by its atomic number, which increases as you move from left to right across a period.

A Period 4 element can be found in the fourth row of the periodic table. The metals with three valence electrons in Period 4 include the elements in Group 13, which is located on the left side of the periodic table. Therefore, a Period 4 element that is a metal with three valence electrons would be located at Position 13.
