What happens when an atom become an ion with a 2-change?

+2 or -2? Either way, nothing special happens.


What change in electron structure occures when a sodium atom becomes a sodium ion?

The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.


How does an atom change to a negatively charged ion what happens to the subatomic partieles?

An atom becomes negatively charged when it gains an electron. However, nothing happens to the subatomic particles.


What is a atom that forms a stable ion but not have an octet structure?

Helium; it has a duplet structure.


What happens when atom looses electron?

If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.


What happens when an atom loses n electron?

If the atom was not a negative ion prior to losing an electron, it becomes a positive ion.


Wta happens whenan atom forms an ion?

When an atom becomes an ion, it is because the atom now no longer has a neutral charge. Nothing really happens besides this, unless it reacts to a different element.


How would an atom change if you had an ion?

When an atom is an ion, it means that it either lost or gained one or more electrons.


What happens to an atom if it gains an electron will it be a negative ion or positive ion?

It will be a negative ion, or in other words, a anion.


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.


What change will occur if an atom gains electrons?

The atom becomes a negative ion.
