For an atom to form an ion, it has to either gain or lose one or more electrons. Usually this happens during a chemical reaction, when an element gains or loses electrons to achieve noble gas configuration.

What is molecular ion?
When an atom loses or gains an electron, it forms an ion. Similarly if a molecule also lose or gain an electron it forms a molecular ion ,e.g CH4+ CO+ etc.
If an atom loses 2 electrons when it forms an ion what is its ionic charge?
+2
What Atom picks up or loses electrons and gains a charge?
An atom that has lost or gained an electron or electrons is called an ion. When an atom loses an electron, it forms a positive ion because the protons then outnumber the electrons. When an atom gains an electron, it forms a negative ion because the electrons now outnumber the protons. A positive ion is called a cation (pronounced "cat-ion" not "ca-shun.") A negative ion is called an anion (pronounced "an-ion" not "an-yun.")
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent atom. =]
What happens when chlorine atoms gain an electron in its outer energy shell?
what happen when an atom what has a lot of electron comes in contact with an atom that has gained an electron
What is the difference between the formation of a positive ion and a negative ion?
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
How does an atom of oxygen get converted into oxide ion when any carbon atom is close to it and vice verse?
This does not happen. Carbon forms covalent bonds with oxygen, not ionic bonds.
When Mg forms an ion will the ion be smaller or longer than the atom?
The ion has a smaller diameter.
What type of ion forms when atom lose electrons?
Losing an ion creates a positive charge. This forms a positive ion.
What happen when you add an electron to an atom?
The atom becomes a negative ion.
When a lithium atom forms a Li plus ion the lithium atom does what?
The lithium atom lose an electron.
A charged particle that forms when an atom transfers electrons?
it is an ion
What forms from a neutral atom or molecule by adding electrons to it?
A positive ion, or cation forms.
What happen when atom an electron?
It becomes a negative ion.
Does a hydrogen ion is a negatively charged hydrogen atom?
No, typically hydrogen forms a positive ion.
When a positive ion forms?
A positive ion is formed when an atom loses one or more then electrons.
What happens when a atom forms an ion?
The atom had either lost or gained one or more electrons forming and ion. Thus the ion has an overall electric charge.
