1.1.1. Intramolecular bonds

Intramolecular links

Generally, the bonds that make up the molecules are strong bonds, such as covalent and ionic . However, the functions of the molecules will depend on other weak ( intermolecular ) bonds that can be easily broken.

Octet rule

The octet rule says that the atoms have a tendency to reach the electronic configuration of the noble gas ( ns 2 np 6 ) that are closest in the periodic table, eight electrons in their outermost or valence shell. To do this, they take, give up or share the electrons necessary to reach that configuration.

An exception to the octet rule is that of hydrogen  or lithium, which have few electrons and tend to have the electronic configuration of helium, also a noble gas but with a 1s 2 configuration .
