Metal with an atomic number of 13
Web6 mrt. 2024 · The table orders elements by atomic number and separates them into three main groups: metals, non-metals, and metalloids (semi-metals). Further elemental groupings include alkali metals, halogens, and noble gases. [2] Using the group (columns) or period (rows) can make the element easier to locate on the table.
