The number of protons and neutrons does not change when an ion forms.
Calcium forms a 2+ ion.
P3- ion (phosphide ion) is formed
potassium
Oxygen usually forms the oxide ion O2-
No. The K+ ion forms because it is isoelectronic with argon.
There has been a change in energy.
Calcium forms a 2+ ion.
cesiums ion
Water disassociates to form the OH- ion or the hydroxide ion, and the H3O+ ion, otherwise known as the hydronium ion.
It forms the Na+ ion.
P3- ion (phosphide ion) is formed
The third period element that forms a 3- ion is sulfur.
The ion has a smaller diameter.
potassium
The ion is awesom
Tellurium typically forms a 2- ion.
Oxygen usually forms the oxide ion O2-
