Gases nobres ou raros

Todos os elementos deste grupo são gasosos à temperatura ambiente e por essa razão os seus pontos de fusão e de ebulição são baixos.

Estes gases são monoatómicos, pois não se agrupam para formar moléculas (estes elementos são bastante estáveis pois apresentam o último nível de energia completamente preenchido com eletrões - dois para o hélio e oito para os restantes).



Características dos gases nobres

São gases à temperatura ambiente.

São gases incolores e inodoros.

Aparecem na natureza sob a forma monoatómica ( átomos isolados).

Existem em quantidades relativamente pequenas, por isso são considerados raros.

Possuem uma reatividade muito baixa, devida à sua estabilidade. Sabe-se atualmente que alguns gases nobres podem reagir para formar outros compostos.
