Identify the element that is in the 3rd period and group 14 of the periodic table.

To identify the element located in the 3rd period and group 14 of the periodic table, we can refer to the structure of the periodic table:

1. Period: This corresponds to the horizontal rows of the periodic table. The 3rd period includes elements from sodium (Na) to argon (Ar).
2. Group 14: This corresponds to the vertical columns of the periodic table. Group 14 elements include carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).

Combining both pieces of information:

• The 3rd period includes the following elements: Na, Mg, Al, Si, P, S, Cl, Ar.
• The element in group 14 within this period is silicon (Si).

Final Answer

The element that is in the 3rd period and group 14 of the periodic table is Silicon (Si).
