The number specified is called the "valence" of the atom for the particular reaction occurring. (Some elements have more than one possible valence.)

Substance produced by a chemical reaction?

A product is a substance formed during a chemical reaction. It is the result of the reaction's course and might have different physical or chemical properties than the reactants.


What are properties in a chemical change?

During a chemical change (chemical reaction) the resulting products have, of course, other properties - compared to the reactants.


Which electron on an atom is the most likely one to be removed during a chemical reaction?

The valence electron, which is the electron located in the outermost energy level of an atom, is the most likely to be removed during a chemical reaction. This is because valence electrons are involved in the formation of chemical bonds and determining an atom's reactivity.


Molecules that furnish electrons during a chemical reaction are called?

Molecules that furnish electrons during a chemical reaction are called reducing agents or electron donors. These molecules undergo oxidation as they donate electrons to another molecule, known as the oxidizing agent or electron acceptor.


Are electrons transferred during a combustion reaction?

Electrons are not typically transferred during a combustion reaction, as it is a rapid chemical reaction involving the oxidation of a fuel source in the presence of oxygen to produce heat and light. Instead, the reaction involves the transfer of atoms and rearrangement of chemical bonds.


What a pigment molecule that transfers electrons during light reaction?

The pigment molecule that transfers electrons during the light reaction is chlorophyll. Chlorophyll absorbs light energy and transfers electrons to the reaction center of the photosystem, initiating the flow of electrons through the electron transport chain. This process is essential for the conversion of light energy into chemical energy during photosynthesis.


Where is the energy which is released during a chemical reaction stored to begin with?

The energy released during a chemical reaction is stored in the chemical bonds of the reactant molecules before the reaction occurs. During the reaction, these bonds are broken, and new bonds are formed, releasing the stored energy in the process.


Is hydrogen lost when a chemical reaction is a reduction?

No, hydrogen is gained during a reduction reaction, not lost. Reduction involves the gain of electrons and hydrogen atoms.


Why atomic number not change during a chemical reaction?

chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.


Are valence electrons lost gained or shared during a chemical reaction?

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.


How many electrons does a nonmetal and metal receive during a chemical reaction?

In general chemical reactions, metals tend to loose electrons and non-metals gain electrons. The no. of electrons loosed by metals is the same as the no. of electrons gained by the non-metals.
