The positivity and negativity of an ion is determined by the number of electrons compared to that of protons. If there are more electrons than protons in the ion, it is considered negative. It becomes negative by gaining electrons, which can happen a number of ways. Simply put, most often it gains electrons by pulling them off of other elements and molecules. The more electronegative an element is, the easier it is for it to do this. Elements are most stable in their "octet" configuration where all of the available spots in an orbital are filled. Elements with less than a perfect octet will rip electrons off of other things.

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
When an atom gains an electron to be stable it becomes?
Electrically Charged or Negatively charged
Is an element with a large negative electron affinity most likely to form a positive ion a negative ion or a neutral atom?
negative ion
How does a positive ion become a neutral atom?
It can be positive or negative depending on if the atom loses or gains an electron. If it gains an electron it becomes negative and if it loses an electron it becomes positive.
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. =]
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
Why are ions charged and thus no longer neutral?
the positive and negative energy is no longer in balance causing the atom to become an ion+ or an ion-
Is chlorine positives or negative?
The atom is neutral; the ion chloride is negative.
Is this atom an ion?
No.... an atom is not an ion.... ions have a positive or negative charge... Atoms are neutral
When an atom gains an electron to be stable it becomes?
Electrically Charged or Negatively charged
Is an element with a large negative electron affinity most likely to form a positive ion a negative ion or a neutral atom?
negative ion
How can a negative charge become neutral?
A negative charge in an atom is neutralized bylosing electrons, so there are the same name protons as there are electronsor having a cation (a positive ion) to form with the negative ion.
Compare the number of electrons of a negative ion to that of the neutral atom include both negative ion and neutral atom in your answer?
The total charge of atoms is equal to the number of positive protons balanced by the total number of negative electrons in a neutral atom which balances the number of electrons.
Is helium an isotope atom or ion?
Helium is a neutral atom that has several isotopes and can become an ion.
How does a positive ion become a neutral atom?
It can be positive or negative depending on if the atom loses or gains an electron. If it gains an electron it becomes negative and if it loses an electron it becomes positive.
What is a positive and negative ion?
when an atom loose electron it become negative ion and when it gains electron it become positive ion
Why are ion charged particles and thus no longer neutral?
the positive and negative energy is no longer in balance causing the atom to become an ion+ or an ion-
