However in ions (different number of electrons) this is not always the case and they can have a positive or a negative charge.

I will keep my sensors carefully trained on changes in ions, humidity, and temperature to predict the weather.

In addition and due to its ability to chelate metal ions it provides corrosion inhibition.

Complete desolvation results in ions that can be detected using mass spectrometry.

In divalent and trivalent ions of the transition metals, the situation is reversed such that the s electrons have higher energy.

This core of electrons in turn pulls in positively charged ions, forming plasma crystals.

In the second case, both electrons of the chemical bond remain with one of the products, resulting in charged ions.

The anion gap is affected by changes in unmeasured ions.

Aqueous solutions or molten bases dissociate in ions and conduct electricity.

If you drink salt water, then you are taking in ions.
