- The image displays a blank periodic table with group numbers (1-18) and period numbers (1-7) labeled.
- The asterisks (*) and double asterisks (**) indicate the positions for the lanthanide and actinide series, which are typically placed below the main table.
- The thick black lines highlight the boundary between metals and nonmetals, running from boron (B) to astatine (At), separating the metalloids (along the line) from metals (to the left) and nonmetals (to the right).
- To solve the problem, one must fill in the elements according to their atomic number, ensuring correct placement in periods (rows) and groups (columns), while respecting the structure shown.
