When chemical bonds are broken and atoms form new bonds in new combinations is called a chemical change. A process like grinding some salt crystals into a fine powder does not involve the breaking of chemical bonds.
When chemical bonds break, the original molecules are dissociated into their constituent atoms or smaller molecules. When new bonds form, atoms rearrange to create new molecules with different properties. This process involves the transfer, sharing, or redistribution of electrons between atoms to form the new bonds.
Based on your question, you have probably noticed that just throwing two chemicals together does not mean that a bond will form. This fact is a good thing, because if every chemical or element that came in contact with another bonded, the world would be constantly reacting. In order for chemicals to bond, a reaction needs to take place. Without adding energy, a reaction will only take place if both compounds or elements will become more stable after the reaction. "Becoming more stable" means that they will both have a full octet of electrons, and a complete energy level.
If you look at a Periodic Table, group one elements have one valence (or outer energy shell) electron. In order to be stable it wants a full octet, so it will react with a group seven element so each element in the compound has a full octet. It does this by giving its electron to the group seven element, because it is far easier to lose one electron than it is to gain seven. There is much more that goes with this process, for example compounds that have more than two elements, but you get the general idea.

It takes energy to break a bond. then the atoms rearrange and can form new bonds releasing energy.
A chemical change occures!
A chemical reaction takes place.
The bonds in a molecule can break and atoms can bond with other atoms.
The arrangement of water molecules start having their chemical bonds break as ice melts. Hydrogen bonds constantly form and break constantly moving everything out of position.
In a chemical reaction, bonds between atoms are broken in reactant molecules. These bonds can be covalent or ionic bonds, which hold the atoms together in the reactant molecules. When these bonds are broken, new bonds can form between atoms, leading to the formation of products.
In a chemical reaction, existing chemical bonds in the reactant molecules are broken, and new bonds are formed to create products. Bonds are rearranged as atoms are reorganized to form different molecules with new properties.
One form of energy that comes from chemical bonds is chemical energy. This energy is stored in the bonds of molecules and is released when these bonds are broken during a chemical reaction. It is a common form of energy found in fuels like gasoline, food, and batteries.
It takes energy to break a bond. then the atoms rearrange and can form new bonds releasing energy.
NO, that's an example of a CHEMICAL change
When bonds break and new bonds form, a chemical reaction has taken place.
A new molecule is formed after a chemical reaction.
The bonds in a molecule can break and atoms can bond with other atoms.
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
2H2 + O2 + 2H2O 2H-H + O=O = 2H-O-H..not shaped like this !! The bonds in the reactants break and the bonds in the products form. The bonds in the H2 and O2 break and the bonds in the water form.
Chemical reactions break the bonds in reactants (compounds) and form new bonds in products (What remains after the reaction).
The arrangement of water molecules start having their chemical bonds break as ice melts. Hydrogen bonds constantly form and break constantly moving everything out of position.
Yes.
That process is called a chemical reaction.
In a chemical reaction, the bonds of the reactants are broken. The atoms will rearrange and new bonds will form.
