A chemical bond is a bondage due to attraction between atoms or molecules that allows the formation of chemical compounds. Chemical bonding provides the energy necessary to hold two different atoms together as Chapter 6 Chemical Bonding Test of a chemical compound. The major types of bonds are Covalent bonds, ionic bonds, hydrogen bonds.These bonds vary in strength electro negativity and ionization energy. Gases are good conductors of electricity at high pressure. Neutron was discovered by Chadwick? Two electrons in the same orbital should have same spin?
