It bonds with other ions, such as hydroxide, to make chemical compounds.

The experiment is repeated with ions of several elements.

Ion association may take place, particularly with ions of higher charge.

I have heard that it is something to do with ions.

There are lots of proteins in the body whose shape and chemical state depends on an equilibrium they keep with H+ ions.

If this works as I plan it to, your city's power system will soon be flooded with negative ions.

Particle beams with heavier ions at higher energy levels can be applied even more precisely.

This is especially significant for chemical systems with transition-metal ions.

It is charged with negative ions which generate a feeling of well-being.

Before a storm the air becomes charged with positive ions.
