chemistry 2.2 - covalent bonding

What are molecules?

When two or more atoms are joined by covalent bonds

What are covalent bonds?

Strong electrostatic attraction between the positive nuclei and the shared electrons

What needs to happen to maintain a covalent bond?

Balance the attraction between the nuclei and the electrons and the repulsion between the electrons as well as the nuclei

What is the bond length?

Distance between the nuclei (distance where repulsive and attractive forces are balanced)

Shat is bond enthalpy?

Amount of energy stored in a bond

How does higher electron density effect a covalent bond?

Stronger attraction = higher bond enthalpy + shorter bond length

What are dative / coordinate covalent bonds?

When an atoms donates both electrons to the covalent bond
