Q:

How are chemical bonds made and broken?

A:

Quick Answer

Chemical bonds are formed when unstable, reactive atoms seek out stable configurations through sharing, donating or receiving valence electrons from other atoms. Bonds are broken down when a specific amount of energy known as the bond energy is applied to the bond.

The bond energy required to break down a bond is dependent on the type of bond. The stronger the bond, the greater amount of energy needed to destroy it. Because covalent bonds are strong, bonds do not spontaneously break down in nature without the application of bond energy. The bond energy can come from different energy sources, such as heat. Endothermic reactions are chemical reactions where heat is absorbed to apply the bond energy necessary to destroy the bond and change the compounds.

Chemical bonds do form spontaneously because atoms are naturally unstable and reactive. The type of bond they form depends on their electronegativity. Smaller differences in electronegativity result in covalent bonds and greater differences result in ionic bonds. The attraction and intermolecular forces of the bonds determine their strength and bond energy. Because chemical bonding involves the transfer of energy, such as atoms donating and receiving valence electrons in ionic bonds, it results in exothermic reactions, or reactions that give off heat energy.

  • Q:

    What is chemical energy?

    A:

    Chemical energy is a type of energy that is stored in the bonds that form between different chemical compounds. These bonds exist between different types of atoms and molecules. The energy that is stored inside of these bonds can be released through a chemical reaction, which usually has a number of different side effects. There are many types of chemical energies that can be found in the world.

  • Q:

    How are chemical bonds formed?

    A:

    Chemical bonds form by the attraction the electrons of one atom to the proton of another atom. Common types of bonds include ionic, covalent and metallic bonds. The formation of the bond links the two atoms through the strong attractive forces, using a bond, a region where the electrons of the atoms interact with one another.

  • Q:

    How do covalent bonds form?

    A:

    Covalent bonds form when atoms share their valence electrons with other atoms to become a more stable molecule. Atoms share their electrons in order to completely fill up their outer-most layer — the valence shell. Two atoms that are covalently bonded have less energy than the individual atoms, making the bonded atoms more stable.

  • Q:

    How are atoms in a compound held together?

    A:

    Chemical bonds, which hold compounds together, are the interactions between the electrons of two or more atoms. An electron's atoms exist in layers or shells, and it is the electrons in the outermost layer that determine how the atom reacts. The ideal state for any atom is to have a full outer shell of electrons; atoms that already have a full outer shell are inert, meaning they do not react. Other atoms chemically bond by sharing, gaining or giving electrons to achieve a full outer shell.
