SucceedSchool.com, learn to succeed. Chemical Bonding. There are three types
of strong chemical bond; ionic, covalent and metallic, and they're all to do with
electrons in the outer electron shells of atoms. Atoms always try to get
complete outer shells of electrons. Some the noble gases in group 0 already have
full outer shells so they're extremely unreactive. Everything else either steals,
looses, or shares electrons. Ionic bonds between metals and nonmetals are where one
atom takes electrons from another atom, such as Group 7 atoms stealing electrons
from Group 1 atoms. This makes both their outer shells complete but it makes the
atoms which gain electrons negatively charged, while the atoms which lose
electrons become positively charged. These equal and opposite electrostatic
charges then attract each other. Covalent bonding between two nonmetals is where
atoms share electrons to fill in the gaps in their shells, but to do so they
have to stick to one another. Metallic bonding is where electrons become
delocalised throughout the metal structure, making metals good conductors
of heat and electricity. For a more detailed explanation of bonding please
