It is called Oxidation number.
An ion can have a positive charge (cation) if it has lost electrons, or a negative charge (anion) if it has gained electrons. The charge of an ion is determined by the number of electrons it has gained or lost during the process of ionization.
A positive ion has lost electrons, resulting in a net positive charge, while a negative ion has gained electrons, resulting in a net negative charge. Positive ions are called cations and negative ions are called anions.
Positive and negative a charge
The positive oxidation number indicates the number of electrons an ion has lost, while the negative oxidation number indicates the number of electrons gained. The oxidation number provides information on the charge of the ion and its ability to form chemical bonds.
The oxidation number of an element is a measure of the number of electrons that an atom of that element has gained or lost to achieve a stable electron configuration. It is a value that is assigned to an element in a compound to help track the flow of electrons in chemical reactions. Oxidation numbers can be positive, negative, or zero, depending on whether the element has lost, gained, or shared electrons.
It could be either. Once a metal produces an ion (an atom with electric charge) it could be positive or negative, depending on number of electrons lost or gained.
That depends on how you change the number of electrons.
This depends on the number of electrons lost or gained. Also important is the electronegativity of a specific atom.
I believe the answer your looking for in an Ion.An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.
An ion is a charged atom that has gained or lost one or more electrons. An ion has an unequal number electrons and protons giving it either a positive or negative charge.
An atom with no electric charge will be called a neutral atom. In a neutral atom, there is a balance of charges, and the number of protons will be equal to the number of electrons. It's really that simple. Compare this to atoms that have an imbalance of charges. These atoms are called ions.
