They established their monatomic and unreactive nature.

这些元素建立了“单原子分子、不反应”的特性。

Elemental nitrogen is a very unreactive and inert material.

元素氮是一个十分不活跃的惰性物质。

So the discovery of the unreactive monatomic gas argon by Lord Rayleigh and William Ramsay in 1895 came as a total surprise.

所以，氩的发现完全出乎人们意料：在1895年，瑞利男爵和威廉·拉姆齐爵士发现了不反应的单分子气体氩。

The reality is that gold and diamonds are completely unreactive, so the benefit of using gold and diamonds over other things is pretty much zero.

实际上黄金和钻石是化学性质稳定的惰性物质，所以黄金和钻石比其他物质更有成效的可能性几乎为零。

Depending on the structure the polymer may be hydrophilic or hydrophobic (likes or hates water), stiff or flexible, crystalline or amorphous, reactive or unreactive.

根据各自的结构不同，聚合物可以是亲水的或憎水的（喜欢或 讨厌水）、硬的或软的、晶体状的或非结晶质的、易起反应的或不易起反应的。
