A chemical bond holds two atoms together. To break the bond, you have to fight against the bond, like stretching a rubber band until it snaps . Doing this takes energy. As an analogy, think of atoms as basketballs.
What is the making and breaking of chemical bonds?
Terms in this set (12) The making and breaking of chemical bonds, leading to changes in the composition of matter
What is the easiest chemical bond to break?
A hydrogen bond is the chemical bond that is the easiest chemical bond to break.
What is the breaking of chemical bonds called?

What causes chemical bonds to break during a reaction?
What causes chemical bonds to break during a reaction? Bond energy is the amount of energy that breaks a bond. Energy is added to break bonds and energy is also released when bonds form. ... In an exothermic reaction, the products have (more or less) energy than the reactants.
What bonds Cannot break?
The bonds that hold atoms together to form molecules are called covalent bonds . They are pretty tough and not easily made or broken apart. It takes energy to make the bonds and energy is released when the bonds are broken.
What are the strongest and weakest bonds?
The ranking from strongest to weakest bonds is: Covalent bond > ionic bond > hydrogen bond > Van der Waals forces . Complete answer: The order from strongest to weakest bonds is: Covalent bond > ionic bond > hydrogen bond >Van der Waals forces.
Are Broken bonds or formed bonds stronger?
-The bonds formed in the products are stronger than the bonds broken the reactants . The bond dissociation energy is the energy needed to break a covalent bond by equally diving the electrons between the two atoms in the bond. -The higher the bond dissociation energy, the stronger the bond.
Is breaking a chemical bond endothermic or exothermic?
Bond-breaking is an endothermic process . Energy is released when new bonds form. Bond-making is an exothermic process. Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.
Are bonds easier to break single or double?
Energy required to break double bond is 614 J while in breaking single bond is 349 J, thus the energy to break double bond is more than single bond so it is stronger than single bond. Double bond is restricted to rotation while single bond rotate freely so, double bond is stronger.
What happens during the formation of chemical bond?
Chemical bonds are the forces of attraction that tie atoms together. Bonds are formed when valence electrons, the electrons in the outermost electronic “shell” of an atom, interact . ... The electrons are still shared between the atoms, but the electrons are not equally attracted to both elements.
What causes chemical bonding?
Chemical bonds are the forces of attraction that tie atoms together. Bonds are formed when valence electrons, the electrons in the outermost electronic “shell” of an atom, interact . ... Atoms with equal or similar electronegativity form covalent bonds, in which the valence electron density is shared between the two atoms.
Which bond is hardest to break?
Intramolecular covalent bonds are the hardest to break and are very stable, being about 98% stronger than intermolecular bonds.
Are hydrogen bonds weak?
Individual hydrogen bonds are weak and easily broken ; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix.
What type of bonds are broken by water or heat?
A hydrogen bond is broken when water vaporizes. Hydrogen bonds are weak bonds between the two water molecules. When heat is applied to water hydrogen...
