Atoms change the position from a molecule to another.
when a chemical change occurs, chemical bonds are broken up
Mono-atomic ions do not undergo a chemical 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.
The chemical composition of foods is changed during cooking.
it stays da same
The chemical nature of the matter is changed; new compounds with new chemical formulas are formed.
Mass is conserved. This means it remains constant.
the number of protons and neutrons
During a chemical change, chemical bonds are broken between atoms in the reactants and new bonds are formed to create products. Energy is either released or absorbed during bond breaking and forming processes. The types and strengths of the bonds determine the overall energy change of the chemical reaction.
They break and new bonds are formed
Catalysts doesn't undergo a chemical change during a chemical reaction.
