Document Summary

The energy that required to remove an electron. The lone pair will repel the bond pair. Some atoms can share more than one pair of electrons to from a multiple bond -- the desired outcome is a full outer shell. A line connecting the atoms concerned is how covalent bonds are depicted. Sometime, one atom can supply both the electron to a covalent bond. The oxonium ion forms when acids are in solution. Breaking the octet rule the standard 8 electrons in a dull outer shell scenario my not always be possible. There may not ve enough electrons to reach a full octet. More than 4 electrons may pair up on bonding. Boron is a metalloid it has both metal and non-metal properties. Expansion of the octet occurs in some elements in group 5,6 and 7. These elements can make 5,6, and 7 covalent bonds respectively under certain conditions, and depending what they bond with.
