If an atom loses an electron, it will be positively charged. An example may make this clearer. A neutral carbon atom has 6 protons and 6 electrons. If you take away an electron, you will have 6 protons and 5 electrons, for a total charge of +6 -5 = +1.
First and foremost, an atom does not lose electrons. An atom of a different element that has a stronger attractive force pulls the electron off the weaker atom. (see electronegativity.
An electron has a charge of -1, and a proton has a charge of +1. If an atom lost 1 electron it would become a +1 charged ion. For example, a sodium atom has 11 protons, each with a +1 charge and 11 electrons, and each with a -1 charge. Adding the charges, +11 + - 11 = 0. If it lost 1 electron, it would have 11 protons, each with a +1 charge and 10 electrons, and each with a -1 charge. Adding the charges, +11 + - 10 = +1. The same is true if an atom of Magnesium loses 2 electrons. 12 protons and 10 electrons = +2 charged ion. Aluminum loses 3 electrons, so it has a +3 charged ion.
If gains electrons it will have a - charge, loses elctrons: + charge
An atom gains one or more electrons to become negatively charged. This reaction is called oxidation.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
An atom becomes an ion if it gains or loses electrons.
When an atoms gains an electron the atom changes into a negative ion and when an atom loses an electron the atom changes into a positive ion.
An atom that has lost or gained an electron or electrons is called an ion. When an atom loses an electron, it forms a positive ion because the protons then outnumber the electrons. When an atom gains an electron, it forms a negative ion because the electrons now outnumber the protons. A positive ion is called a cation (pronounced "cat-ion" not "ca-shun.") A negative ion is called an anion (pronounced "an-ion" not "an-yun.")
It either gains, loses, or shares electrons.
A net charge results when an atom gains or loses electrons. If it loses electrons, it gains a positive charge, if it gains them, it gains a net negative charge.
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
Ions are formed when an atom gains or loses electrons. When an atom loses electrons the Ion that is formed has a positive charge.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
It is called an ion.
An atom becomes an ion if it gains or loses electrons.
an ion
This neutral atom become a cation or an anion.
When an atoms gains an electron the atom changes into a negative ion and when an atom loses an electron the atom changes into a positive ion.
Matter becomes charged when it loses or gains electrons. When an atom is neutral (no charge) it has an equal number of protons and electrons. But when it loses electrons, it becomes positively charged. When it gains electrons, it becomes negatively charged. Hope I helped! :)
They are lost. If it has a plus sign beside the ion charge, that means the atom loses electrons. But if it has a negative sign for the ion charge, that means that the atom gains electrons.
