What happens to the atoms of a substance in a chemical reaction?
Answer: Chemical bonds are forces that hold atoms together to make compounds or molecules. Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.
During chemical reactions, the bonds that hold molecules together break apart and form new bonds, rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form; without this energy, the reaction cannot take place, and the reactants remain as they were.
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Chemical reactions No atoms are created or destroyed in a chemical reaction. This means that the total mass of the reactants is the same as the total mass of the products. We say that mass is conserved in a chemical reaction.
No atoms are destroyed, and no new atoms are created in chemical reactions. reactants The bonds between atoms are broken and rearranged as new bonds to make the new product.
In burning, the two atoms or molecules will combine and release energy. Usually one of the two molecules is oxygen or something else chemically like it called an oxidizer. When the molecules combine and release energy, it is released in the form of heat and often light. Hydrogen burns with oxygen and produces water.
In physical changes no new materials are formed and the particles do not change apart from gaining or losing energy. Particles stay the same unless there is a chemical change whether the matter is solid, liquid or gas. Only their arrangement, energy and movement changes.
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. Most of an atom is empty space.
During a chemical reaction, the bonds between the atoms in the reactants are broken and the atoms bond in new ways to form products that are physically and chemically different from the reactants.
In the reaction, the atoms of the starting substances are rearranged, forming new substances that have different properties. The number of atoms and the amount of mass are the same before and after the reaction takes place; thus mass is conserved.
Remember that in a chemical reaction, matter is neither created nor destroyed and atoms cannot change their identity (e.g. a carbon atom can’t become an Iron atom); this means that you have to have the same number of each type of atom on each side of the chemical equation.
During a chemical reaction no atoms are created or destroyed. The atoms are rearranged. This results in the formation of new substances with different properties to the starting substances.
