What happens to the number of atoms after a chemical change?
No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Does the number of atoms change in a chemical change?
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Are the number of atoms the same after a chemical reaction?
The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products.

Is the number of atoms same before and after chemical reaction?
According to the law of conservation of matter, the number of atoms before and after a chemical reaction should be equal, such that no atoms are, under normal circumstances, created or destroyed.

Can atoms be destroyed in physical reaction?
It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed.

Are atoms lost or gained in a chemical change?
No atoms are added or taken away from the system, so the mass stays the same. Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants.

Can atoms be changed or destroyed?
According to the law of conservation of energy, the matter cannot be created nor be destroyed. Hence, an atom cannot be destroyed and it cannot be broken into smaller particles. The atoms mainly consist of three primary particles and that is electron, proton, and neutron.

Which best describes what happens to the atoms in a chemical reaction?
According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made.

Are atoms lost or gained during a chemical change?
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.

What happens to the atoms in the reactants during a chemical reaction quizlet?
What happens to the atoms in the reactants during a chemical reaction? When a reactant participates during a chemical reaction, the bonds between the atoms of the reactants are broken and rearranged to form a new bond. The reactants undergo changes and transformation in order to produce new substances.
