Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.
Ions are formed when atoms again or lose electrons. Cations are farmed when atoms lose electrons and anions are formed when atoms gain electrons.
An oxidized substance.
Metals forms cations, losing electrons.
Positive.
Electrons are both gained and lost. Electrons are both gained and lost.
An atom that has gained an electron becomes a negatively charged ion.
Usually three will be lost.
They are gained.
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.
Electrons are both gained and lost. Electrons are both gained and lost.
Oxidation is the loss of electrons. Reduction is the gain of electrons. The oxidizing agent is reduced. The reducing agent is oxidized. Cu goes from 0 to +2, it lost electrons S went from +6 to +4, it gained electrons I went from 0 to +5, it lost electrons N went from +5 to +4, it gained electrons.
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
An atom that has gained an electron becomes a negatively charged ion.
Shared
it has gain 4 electrons
-3 electrons are gained,i.e,3 electrons are lost by Al and 3 electrons are gained by the other atom nearby.
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
Usually three will be lost.
They are gained.
Chlorine gain electrons.
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.
