Lewis Dot Structures

Front

What is a valence electron?

Back

An electron found in the outermost shell of an atom.

Front

Which atom will never be in the middle of a Lewis Dot structure?

Back

Hydrogen (H) will never be in the middle.

Front

According to the octet rule, most elements need how many valence electrons?

Back

8 valence electrons.

Front

How many valence electrons does Carbon have?

Back

Carbon has 4 valence electrons.

Front

How many lone pairs does NH3 have?

Back

NH3 has 1 lone pair.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is a Lewis Dot Structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What does a single bond represent in a Lewis Dot Structure?

Back

A single bond represents one pair of shared electrons between two atoms.

Front

What is the significance of lone pairs in Lewis Dot Structures?

Back

Lone pairs represent non-bonding electrons that can affect the shape and reactivity of the molecule.

Front

How do you determine the central atom in a Lewis Dot Structure?

Back

The central atom is usually the least electronegative atom or the atom that can form the most bonds.
