And eventually it can combine with a nearby silver ion to turn it into a neutrally-charged silver atom.

最终它与附近的一个银离子结合，使其转化为带中性电的银原子。

Such nanoparticles, designated as EbNPs, also carry highly active silver ions that attach to and kill bacteria, but their core is biodegradable and not harmful to the environment.

这种纳米粒子被叫作木质芯纳米颗粒，它也含有活跃的银离子，并附着在真菌上并将其杀死，但是这种木质芯能够生物降解，并对环境无害。

The silver ions in the exposed halide crystals, the ones with metallic silver in them, will have more reactions with the developer, creating more metallic silver in those grains.

曝光的卤化物晶体含有金属银，该晶体的银离子与显影剂反应更加充分，从而生成更多的金属银。

Where conditions were right, silver ions in the water reacted with ionic compounds, or salts, in the limestone to make insoluble silver compounds that fell out of solution.

在条件合适的情况下， 水中的银离子会与石灰石中的离子化合物或盐发生反应，生成不溶性的银化合物， 这些化合物会从溶液中析出。
