The growing radiation from those first stars ionized hydrogen atoms, split them back into protons and electrons.

随着初代恒星发出的辐射越来越大，电离的氢原子再次被分解为质子和电子。

This is known as ionizing radiation because an atom that has lost or gained electrons is called an ion.

这个叫做电离辐射因为一个已经失去或得到电子的原子叫做离子。

If you paid attention, you learned how pure water ionizes to form hydronium and hydroxide ions in reversible reactions.

也会出现0以下或是14以上的时候但那只会出现在一些极端条件下。
