An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.
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.
18 electrons
The charge of an ion depends on the number of electrons gained or lost. Since the charge of an ion is not mentioned in this case, it is typically neutral as an atom, having an equal number of protons and electrons.
loses 2 electrons to form a calcium ion with 2+ charge
The charge on a carbonate ion is -2; therefore, the ion has two more electrons than protons.
an ion
An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
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.
An example of a substance that carries an electrical charge is an ion. Ions are atoms or molecules that have gained or lost one or more electrons, resulting in a positive or negative charge. These charged particles are essential for many biological and chemical processes in living organisms.
Ions. Cations have lost electrons and have a positive charge. Anions have gained electrons and have a negative charge.
A negative ion has one or more electrons, so it carries a negative charge wich depends on the number of electrons it gained. A neutral ion did not gain or lose any electrons, so it carries no charge, therefore being neutral.
It is a negative charge
Each electron has a 1- charge, so an atom that has gained 5 electrons has a charge of 5-.
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.
-1, since each electron has a charge of -1.
Positive
