An atom has an equal amount of Electrons and Protons, but an ion is a particle with an uneven amount of Protons and Electrons. A Cation, having more Protons than Electrons and an Anion, having more Electrons than Protons.

∙ 11y agoIons are atoms that have either given up or taken on electrons while in a solution. There is a charge to an ion depending on the number of electrons that have been exchanged. An atom has no missing or extra electrons and has no charge whether or not it's in a solution.

∙ 12y agoAn atom is what you would locate on the Periodic Table where its proton number matches (equals) the number of electrons the atom holds. An ion has a different electron number than that of the proton number in an atom. Therefore, it becomes negatively of positively charged.
Example:
Fe (iron) as an atom has 26 protons and 26 electrons.
Fe-2 and Fe+2 are ions of Iron because the either have too many or too little electrons.
Negatively charged ions are anions
Positively charged ions are cations.

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. =]
A Mg atom differs from a Mg2 plus ion in that the Mg atom has?
The Mg atom has more electron than the Mg+2 ion.
Why is the chloride ion larger than the chloride atom?
The chloride ion is an anion, having one more electron than the chlorine atom.
When electron transfer results in an ion larger than the original atom?
An atom that has gained one or more electrons, becoming a negative ion, is larger than its parent atom.
What can be concluded if an ion of an element is smaller than an atom of the same element?
The ion is positively charged because it has fewer electrons than the atom.
What is an example of an atom of an element has properties that are very different from those of an ion of the same element?
its ion and atom properties differences is atom is like science ion-chemistry
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. =]
How is an ion different from an atom of the same substance?
an ion has a full "shell"
What does -ion mean?
An ion is an atom with a positive (+) or negative (-) charge. This is because the atom has a different amount of electrons than its number of protons (aka atomic number).
A lithium ion is different than a lithium atom because it?
The Li ion is different from the atom because it has positive charge. (Lithium is group 1 element and these lose 1 electron to form for example :Li+ , Na+ etc)
If an atom has lost more protons than electrons it is called a ion?
If the atom has more electrons than protons, then yes it is an ion.
A negative ion is than its parent atom?
A negative ion is larger than its parent atom because of its additional electron(s).
What is the essential difference between an ion and an atom?
An ion is an atom that has a different number of electrons than normal. That makes it positively or negatively charged. Normally, atoms have the same number of electrons as they have protons. If the atom has lost one of more electrons, it will be a positive ion. If it has gained one or more electrons, it will be a negative ion.
Is a positive proton different than a positive ion?
A positive ion is a type of atom with less electrons than usual. A proton is a subatomic particle that makes up atoms.
Is an atom of an element with a different number of neutrons called ion or isotope?
ion
When an atom of chlorine forms an ionic bond with an atom of sodium does the atom of chlorine become an ion with a smaller or larger radius than the atom of chlorine?
It becomes an ion with a larger radius than the atom of chlorine
A Mg atom differs from a Mg2 plus ion in that the Mg atom has?
The Mg atom has more electron than the Mg+2 ion.
