Guida verificata passo dopo passo1
Understand the layout of the periodic table: groups are the vertical columns numbered 1 to 18, and periods are the horizontal rows numbered 1 to 7.
Identify group 14, also known as the carbon group, which includes elements like Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb).
Locate period 3, which is the third row from the top of the periodic table. Elements in this period have three electron shells.
Find the element that is both in group 14 and period 3 by looking at the intersection of the third row and the 14th column in the periodic table.
Confirm that the element at this position is Silicon (Si), which is the correct answer.
