10.4 Ionic Bonding: Lewis Symbols and
The pair left.
The Lewis model shows why diatomic molecule form.
The Lewis model predicts that chlorine is a diatomic molecule.
The other halogens are the same.
The Lewis model predicts correctly again.
H2 is a molecule of hydrogen.
Two atoms may share more than one electron pair in the Lewis model.
Double bonds are stronger than single bonds.
The structure of N2 is called the Lewis structure.
The Lewis structure for N2 has 10 electrons since each N atom has five electrons.
Triple bonds are stronger than double bonds.
When we look at nitrogen in nature, we find that it is a diatomic mole with a strong bond between the two nitrogen atoms.
The bond is so strong that it is difficult to break.
The properties of compounds are predicted by the Lewis model.
It explains why certain combinations of atoms do not form a molecule.
We can write a good Lewis structure for H2O, but not for H3O.
The Lewis model predicts that H2O should be stable, while H3O should not be.
The hydronium ion is stable in water.
There are other possible combinations for hydrogen and oxygen according to the Lewis model.
H2O2, also known as hydrogen peroxide, is often used as a bleach.
The sharing of one or more electron pairs in the space between them causes the attraction between two covalently bonding atoms.
Individual molecule are the fundamental units of covalently bonded compounds.
There are a number of ways in which these molecule can interact with one another.
