Elements numbered 11-18 in the Periodic Table do not comprise a single family, but rather they include two distinct groups. Elements 11 (sodium) through 12 (magnesium) are metals in the s-block, while elements 13 (aluminum) through 18 (noble gases) span both p-block and transition metals. The elements from 13 to 18 include the boron group, carbon group, nitrogen group, oxygen group, halogens, and noble gases, each characterized by different properties and behaviors. Therefore, they represent a range of families rather than a cohesive group.
