Consider two small solids which are comprised of six atomic bonds each.

想象个小块固体，这个固体都有六个化。

In part, these PFAS are effective because their chemical bonds are incredibly strong.

在某种程度上，这些 PFAS 有效原因是因为它们化非牢固。

Here you might have those same bonds.

破坏这些化关之一是通过氧化。

To put it chemistry specific, it has two unpaired electrons, which really want to form chemical bonds.

具体到化，它有个不成对电子，它们真想形成化。

Because it's an amorphous solid with bonds of varying strength, glass doesn't have an exact melting point.

因为玻璃是一种由强度不定化链接成非晶固体，它没有确定熔点。

And also like graphite and diamond, the different forms that they take are all about bonding differences.

石墨和金刚石一样，化差异也会导致不同网状结构。

Well, in nature, most things decompose because bacteria breaks down the chemical bonds that hold a substance together.
