Yes!
Loss of electrons: A substance loses electrons, leading to an increase in its oxidation state. Gain of oxygen or loss of hydrogen: The substance reacts with oxygen or loses hydrogen atoms. Increase in oxidation state: The oxidation number of the substance increases. Formation of products: New compounds are formed as a result of the oxidation process.
An element that decreases its oxidation number in a chemical reaction is undergoing reduction. In the given reaction, the element that is reduced is the one that gains electrons and decreases its oxidation number.
The oxidation number of an elementary substance is zero because there is no transfer of electrons between atoms of the same element in a compound. Each atom in an elementary substance is considered to have an oxidation number of zero.
In the reaction of aluminum with oxygen to form aluminum oxide (Al + O2 -> Al2O3), the oxidation number of aluminum changes from 0 to +3, while the oxidation number of oxygen changes from 0 to -2. This indicates that aluminum is undergoing oxidation, while oxygen is undergoing reduction in the reaction.
Oxidation means there's an increase in oxidation number. Reduction means there's a decrease in oxidation number.

A substance that shows a decrease in oxidation number during a chemical reaction is being reduced. Reduction involves a decrease in the oxidation number of an element. This indicates a gain of electrons by the substance.
Oxidation has three main meanings in science, 1) An substance gaining oxygen 2) A substance loses electrons 3) A substance increases in oxidation number (ox. State)
No. Oxidation is the loss of electrons by an atom, or equivalently an increase in the oxidation number of that atom. Rust formation is one example of oxidation.
Oxidation means there's an increase in oxidation number. Reduction means there's a decrease in oxidation number.
Chlorine has an oxidation number of +5 in compounds such as perchlorate (ClO4-). This is due to the electronegativity of oxygen, which causes chlorine to have a higher oxidation state in the compound.
Chlorine has an oxidation number of +1 in compounds with metals such as sodium chloride (NaCl) or potassium chloride (KCl).
Of course not. No change in neutrons. Number of electrons decrease
