Oxidation occurs when an atom molecule or ion loses one or more electrons in a chemical reaction. When oxidation occurs the oxidation state of the chemical species increases.

When two or more atoms have ions?
Any atom or molecule with a net charge either positive or negative is known as an ion. An ion consisting of a single atom is a monoatomic ion an ion consisting of two or more atoms is referred to as a polyatomic ion.
When one reactant gains electrons during a redox reaction it is said to have become?
The element that “gains electrons” in a redox reaction is said to be reduced and will have a decrease in its oxidation number. In the reaction above the oxidation number of oxygen has decreased from zero to –2 it has “gained electrons” and has been reduced.
When one atom in a molecule donates electrons and another atom accepts them they participate in?
The correct answer is (2) ionic bond. An ionic bond is a type of chemical bond that forms when an electron is transferred from one atom to another….
When one atom loses an electron and another atom accepts that electron A?
Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. The atom that loses the electrons becomes a positively charged ion (cation) while the one that gains them becomes a negatively charged ion (anion).
What kind of bond is formed when one atom gains an electron and another atom loses an electron?
Ionic bonding involves a transfer of an electron so one atom gains an electron while one atom loses an electron. One of the resulting ions carries a negative charge (anion) and the other ion carries a positive charge (cation). Because opposite charges attract the atoms bond together to form a molecule.
What is the gain of electrons?
The gain of the electrons is known as reduction whereas the loss of electrons is known as oxidation. Generally one atom loses the electron (s) and gets oxidized which electron is then gained by another atom to get reduced. Hence both the processes occur hand-in-hand and such reactions are known as redox reactions.
What reactant gains electrons over the course of the reactions?
Explanation: As you know a redox reaction involves the transfer of electrons from a chemical species that loses electrons to a chemical species that gain electrons. The chemical species that loses electrons is undergoing oxidation and the chemical species that gains electrons is undergoing reduction.
Is a particle that gains electrons called a cation?
When an atom gains electrons (which are negatively charge) the ion formed is negatively charged and is called an anion. If an atom loses electrons the ion formed in positively charged and is called a cation.
When a molecule gains hydrogen atoms what does it become?
A molecule becomes reduced when NAD+ gains a hydrogen atom because it gains an electron causing it to become reduced.
What is the process of gaining or losing electrons?
Oxidation is the process of losing an electrons while reduction is the process of gaining them. Any chemical that causes another chemical to lose electrons (become oxidized) is called an oxidizing agent. Conversely any chemical that causes another chemical to gain electrons is called a reducing agent.
How do you find the gain or loss of electrons?
Subtract the charge from the atomic number if the ion is positive. If the charge is positive the ion has lost electrons. To determine how many electrons are left subtract the amount of charge from the atomic number.
