The neutral radium atom has 88 electrons, the radium cation has 86 electrons.
Radium Ra forms double positive ions (cations) symbol Ra++ or Ra +2
The radium ion is Ra(2+).
If an ion gains an electron that means the ion will be negatively charged.The name of that ion is called anion. On the other hand, if it loses and electron the ion will be positively charged, and the name of that ion is called cation.
An example of an ion that is missing an electron is the sodium ion (Na+). In its neutral state, sodium has one electron, but when it loses that electron, it becomes positively charged as a Na+ ion.
16 protons and 18 electrons

Bromine will gain one electron when forming an ion to achieve a full outer electron shell. This will give it a stable electron configuration.
If an ion gains an electron that means the ion will be negatively charged.The name of that ion is called anion. On the other hand, if it loses and electron the ion will be positively charged, and the name of that ion is called cation.
Fluorine gains one electron to form a fluoride ion.
A chloride ion has gained one electron to achieve a full outer shell and achieve a stable electron configuration. Therefore, a chloride ion has 18 electrons.
A chlorine atom will gain one electron when forming an ion. That will give the ion a charge of 1-.
ion can be produced when atom lose or gain electron when it lose electron it's converted to cation(+) but when gained it's converted to anion(-)
It may be possible to bombard Radium 15 with protons, creating Radium 16. Radium 16 has a fast decay rate. This would release large amounts of energy.
When iodine becomes an ion, it typically gains an electron to form a negative ion (iodide ion). This addition of an electron causes the ion to become slightly larger in size due to the increased electron-electron repulsion, which can lead to a slight expansion of its electron cloud and thus the overall size of the ion.
The electron configuration for the Co2 ion is Ar 3d7.
