What would be the charge on a negative ion?
Εδώ είναι γιατί:
* Atoms are normally neutral: They have an equal number of protons (positive charge) and electrons (negative charge).
* Negative ions form by gaining electrons: When an atom gains one or more electrons, it has more negative charges than positive charges, resulting in a net negative charge.
Παραδείγματα:
* Chloride ion (Cl-) has gained one electron.
* Oxide ion (O2-) has gained two electrons.
