poor metalлегкий метал

(Их температуры плавления и температуры кипения отличаются от переходных металлов. Их электроотрицательность выше по сравнению с переходными металлами; лёгкие металлы являются менее твёрдыми по сравнению с ними. Они отличаются от металлоидов, однако, по их значительно большей температуре кипения они находятся в одной строке расширенной таблицы)
