Verified step by step guidance1
Identify the group number of carbon on the periodic table. Carbon is in group 14 (also known as group IV).
Determine which elements are metalloids. Metalloids have properties intermediate between metals and nonmetals and are typically found along the 'stair-step' line on the periodic table.
Look at the elements in group 14 and find which ones are metalloids. In group 14, the common metalloids are silicon (Si) and germanium (Ge).
Check the period (row) number for these metalloids. Silicon is in period 3, while germanium is in period 4.
Conclude that the metalloid in period 4 and group 14 (same group as carbon) is germanium.
