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.
Electrons are both gained and lost. Electrons are both gained and lost.
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.
Usually three will be lost.
They are gained.
An atom that has gained an electron becomes a negatively charged ion.
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.
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.
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.
An atom that has gained an electron becomes a negatively charged ion.
An ion
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.
An atom that has gained or lost electrons is called an ion. If it gains electrons, it becomes a negatively charged ion (an anion), while if it loses electrons, it becomes positively charged (a cation).
Valence electrons can be both lost and gained during a chemical reaction, depending on the types of elements involved. For example, in ionic bonding, valence electrons are typically lost or gained to achieve a full outer shell. In covalent bonding, valence electrons are shared between atoms to complete their outer shells.
