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.

∙ 9y agoWhen 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.

What changes do chemical reactions involve in chemical bonds that join atoms in compounds?
The bonds in a molecule can break and atoms can bond with other atoms.
What happens to the arrangement to the molecules as ice melts?
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.
What happens to chemical bonds in a chemical reaction?
It depends on the type of reaction that is forming the bonds If the reaction is exothermic energy is given out when new bonds are formed If the reaction is endothermic energy is taken in when new bonds are formed -Hope that helps!! well it does thanks
What happens when two oxygen molecules combine to form a molecule of oxygen?
Chemical bonds are formed and energy is released.
Why do elements stick together when they form chemical bonds?
A chemical bond requires energy to break it, therefore if the bond is strong enough then the atoms "stick" together
What happens when chemical bonds break and bonds form?
It takes energy to break a bond. then the atoms rearrange and can form new bonds releasing energy.
Is a physical change what happens when chemical bonds break and new bonds form?
NO, that's an example of a CHEMICAL change
When bonds break and new bonds form?
When bonds break and new bonds form, a chemical reaction has taken place.
What happends when bonds break and new bonds form?
A new molecule is formed after a chemical reaction.
What changes do chemical reactions involve in chemical bonds that join atoms in compounds?
The bonds in a molecule can break and atoms can bond with other atoms.
What happens to the bonds of the products during a chemical reaction?
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.
Which bonds break and which new bonds form?
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.
How chemical reactions affect chemical bonds in compound?
Chemical reactions break the bonds in reactants (compounds) and form new bonds in products (What remains after the reaction).
What happens to the arrangement to the molecules as ice melts?
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.
Is it a chemical reaction or a chemical property when atoms break and form a new bonds?
Yes.
What initiates chemical reactions by breaking bonds in the reactants?
That process is called a chemical reaction.
What happenes to chemical bonds during chemical reaction?
In a chemical reaction, the bonds of the reactants are broken. The atoms will rearrange and new bonds will form.
