Lewis dot structures

Front

What is a Lewis dot structure?

Back

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

How many valence electrons does hydrogen have?

Back

Hydrogen has 1 valence electron.

Front

What is the maximum number of electrons that can occupy the valence shell of an atom?

Back

The maximum number of electrons that can occupy the valence shell of an atom is 8, following the octet rule.

Front

What is the significance of noble gases in relation to electron configuration?

Back

Noble gases have a full valence shell, making them stable; other elements tend to gain or lose electrons to achieve a similar electron configuration.

Front

How many bonds can carbon form?

Back

Carbon can form 4 bonds.

Front

What is the correct Lewis dot structure for neon (Ne)?

Back

Neon has 8 valence electrons represented as dots around the symbol Ne, indicating a full valence shell.

Front

What does it mean for an atom to be stable?

Back

An atom is stable when its valence shell is full, typically with 8 electrons (or 2 for hydrogen and helium).

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full valence shell of 8 electrons.

Front

What is a lone pair in a Lewis dot structure?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.

Front

How do you determine the number of bonds an atom can form?

Back

The number of bonds an atom can form is determined by the number of electrons it needs to gain, lose, or share to achieve a full valence shell.
