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.
An atom becomes negative in charge when there is one or more extra electrons in its outer layer.
An atom becomes a negative ion when it gains one or more electrons.
This is by gaining (-) or losing (+) electrons
This happens when one or more electrons are picked up from a reducing agent
An atom become an ion after losing or gaining electrons.
it gains one or more electrons
When this element gain electrons.
when it gains one or more electrons
it will become a negative ion due to the negative charge of electron
Electrically Charged or Negatively charged
negative ion
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.
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. =]
it will become a negative ion due to the negative charge of electron
the positive and negative energy is no longer in balance causing the atom to become an ion+ or an ion-
The atom is neutral; the ion chloride is negative.
No.... an atom is not an ion.... ions have a positive or negative charge... Atoms are neutral
Electrically Charged or Negatively charged
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.
negative ion
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.
Helium is a neutral atom that has several isotopes and can become an ion.
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.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
the positive and negative energy is no longer in balance causing the atom to become an ion+ or an ion-
