Lose electrons is oxidation. To gain electrons is reduction.
ion
atoms gain and lose electrons, so they can have a full outer shell of 8 electrons (or two electrons if its the innermost shell) when atoms lose electrons it is called oxidation and when they gain electrons they are said to be reduced. OIL RIG is most commonly used to help remember that oxidation is loss and reduction is gain of electons. when atoms lose electrons they are left with a positive charge and when they can electrons they have a negative charge.
An ion.
They become cations, positive ions.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
When atoms gain or lose electrons, they become negatively charged if they gain electrons (anions) or positively charged if they lose electrons (cations). These charged atoms are known as ions.
If atoms lose electrons they will have a positively charged ion called a cation. If they gain electrons, they will have a negatively charged ion called an anion.
That is called a cation. They then have a positive charge.
Atoms that gain or lose electrons become ions, not molecules. Ions are charged particles due to an imbalance of protons and electrons. Molecules are formed when atoms are bonded together by sharing electrons.
yes, this is called oxidation
Metals that lose electrons easily are called "reactive metals" or "electropositive metals." These metals have low ionization energies, which allow them to readily give up electrons to form positive ions.
Electrons in the outer most shell are called Valence Electrons.
