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

Are valence electrons lost gained or shared during a chemical reaction?
They are lost.
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.
Molecules that furnish electrons during a chemical reaction are called?
electron donors
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.
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
Are valence electrons lost gained or shared during a chemical reaction?
They are lost.
Does the amount of energy change during a chemical reaction?
duuh...of course it does
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.
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.
Do non-metals gain electrons in chemical reactions?
during a chemical reaction valence electrons are most always transferred
Molecules that furnish electrons during a chemical reaction are called?
electron donors
Which electron on an atom is the most likely one to be removed during a chemical reaction?
Electrons called valence electrons are most likely removed. These are the outermost energy level electrons.
During a chemical reaction atoms rearrange their valence electrons in order to become?
broken and recreated or mixed with other chemicals
Is the electron configuration of an atom related to its tendency to give up or gain electrons during a chemical reaction?
tangina nyo
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
What is an electron called in the outermost energy level?
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
