The electron has the least mass of the three mentioned. That's why the valance electrons are the determining factor in most reactions. The proton closely follows the neutron because they are exactly the same except for charge. This leaves the the electron as the lightest sub-atomic particle.

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.
When an atom gains or looses electrons what to the charge of atom?
When an atoms gains an electron the atom changes into a negative ion and when an atom loses an electron the atom changes into a positive ion.
Why some atom lose electron and some gain electron?
Atom lose electron to form positive ion and some gain electron to form negative ion.
If an electron is added to a neutral atom the atom becomes what?
it will become a negative ion due to the negative charge of electron
What happens when a atom gains an electron?
When an atom gains an electron it becomes an ion with a charge of negative one. This charge comes from the electron's negativity, which changes the atom's balanced ratio of electrons to protons.
Which is smallest in size an ion electron neutron or atom?
electron is the smallest
How does sodium atom form an ion?
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
Which has a linear size or radius closest to the radius of a neutron star?
Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter
Which of these is not a subatomic particle proton ion neutron or electron?
Ion.
How can a charged atom attract a neutron?
A neutron has no charge, so a charged atom (ion) cannot attract a neutron.
Smallest is a atom or ion?
atom
Which type of atom has and overall positive charge?
A charage atom called : ion proton positive charge location of proton and electron electron negative charge (Proton) in the neutron (Electron) orbiting the nucleus if it's (+) means proton (POSTIVE) if it's (x) means electron (NEGTIVE)
An atom that gains an electron gains what type of ion?
an atom that gains an electron becomes a negative ion, called an anion.
What subatomic particles are closest in mass proton and neutron neutron and electron proton and electron electron and ion?
Mg+2 and Br-1
A sodium ion differs from a sodium atom in that the sodium ion?
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
When an atom loses an electron it loses a?
Removal of an electron from an atom leaves a positively charged ion.
When an atom gains an electron the atom becomes an ion that?
yes...on gaining an electron, the atom becomes an anion i.e. negatively charged ion.
