Electrons
The cause is the interaction between valence electrons.
Metals form cations and non-metals form anions.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Charged atoms are called ions.
why atoms of group 0 elements do not form ions

Negative ions form when atoms GAIN valence electrons.
Ions, charged atoms
unstable atoms
Because they want to.
No. Atoms of an element lose or gain electrons to form ions.
ions
Negative ions are formed when atoms accept electrons.
+1 ions.
Electrons
No. Beryllium has only two valence electrons and forms ionic bonds with chlorine, not covalent bonds. Beryllium atoms form 2+ ions, and chlorine atoms form 1- ions in order to form the ionic compound beryllium chloride, BeCl2.
