Covalent Bonding Flashcards
1
Q
What elements are involved?
A
Two non-metals are involved in covalent bonding
2
Q
Are ions formed?
A
An ion is not formed as covalent bonds do not lose or gain electrons, they share.
3
Q
Behaviour of valence electrons
A
Both atoms in the bond contribute one valence electron in order to form a shared pair.
4
Q
Electrical conductivity
A
Covalent bonds do not conduct electricity because the molecules are neutral and there are no charged particles to move freely and carry charge.
5
Q
Solubility
A
Covalent bonds are soluble in non-polar solvents, however they are insoluble in polar solvents such as water
6
Q
Additional properties
A
Low boiling and melting points and they are soft and flexible.
7
Q
Examples
A
SiO2 - Silicon Dioxide
Dinitrogen Trioxide - N2O3
