The Valence shells of all atoms are being filled
to the lowest energy {most stable}
Bohr diagrams can show simple
covalent bonds - note where the
shared electrons are

point form
Atoms overlap and share an unpaired electron between them
Non-metallic atoms share electrons to form the bond
Covalent molecule is a group of atoms bound by electron sharing
The pair of electrons being share is called the "Bonding pair"
Co =sharing/together
Valent = Valence = Latin for strength/power
Contains a positive ion, (metals) and a negative ion (non-metal
one or more e transfers from each metal aton to each non-metal ion
When atoms touch their valence electrons interact
The more stable an atom, ion or compound the lower the energy state. {Think Noble Gases}
Compounds can achieve this lower energy state by
1 Atoms of metals may lose electrons to other atoms forming cations
2 Atoms of non-metals may gain electrons from other atoms forming anions
3 Atoms may share electrons
2 e
1 e
7 e
What grouping an element is put into and how they react is dependent on how many electron they have.
For us to see this we map out the electrons using the Niels Bohr system.
