What is the Lewis dot structure for a molecule?

Back

The Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

How do you determine the correct Lewis dot structure for a molecule?

Back

To determine the correct Lewis dot structure, count the total number of valence electrons, arrange the atoms, and distribute the electrons to satisfy the octet rule.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Which elements typically form covalent bonds?

Back

Nonmetals typically form covalent bonds.

Front

What is the difference between a metal and a non-metal?

Back

Metals are typically good conductors of heat and electricity, malleable, and ductile, while non-metals are poor conductors and are often brittle.

Front

What is the significance of the right side of the periodic table in covalent bonding?

Back

The right side of the periodic table contains nonmetals, which are more likely to form covalent bonds by sharing electrons.

How do you identify a non-metal on the periodic table?

Back

Non-metals are found on the right side of the periodic table, typically in groups 14-18.
