Lewis Dot Structures - Ionic and Covalent

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.

Front

What does the octet rule state?

Back

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

Front

How do you represent a covalent bond in a Lewis Dot Structure?

Back

A covalent bond is represented by a pair of dots or a line between two atoms, indicating that they share a pair of electrons.

Front

What is the Lewis Dot Structure for ammonia (NH3)?

Back

The Lewis Dot Structure for ammonia shows nitrogen in the center with three hydrogen atoms bonded to it, and one lone pair of electrons on nitrogen.

Front

How is a double bond represented in a Lewis Dot Structure?

Back

A double bond is represented by two pairs of dots or two lines between two atoms, indicating that they share two pairs of electrons.

Front

Which element is typically found in the center of a Lewis Dot Structure?

Back

The least electronegative element is typically found in the center of a Lewis Dot Structure.

Front

What is the correct Lewis Dot Structure for an O2 molecule?

Back

The Lewis Dot Structure for O2 shows two oxygen atoms connected by a double bond, with each oxygen having two lone pairs of electrons.

Front

Which elements do not follow the octet rule?

Back

Elements like hydrogen and helium do not follow the octet rule; hydrogen is stable with two electrons.

Front

What is the Lewis Dot Structure for fluorine (F2)?

Back

The Lewis Dot Structure for fluorine (F2) shows two fluorine atoms connected by a single bond, with three lone pairs of electrons on each atom.

Front

What should you do if you don't have enough electrons to satisfy the octet rule?

Back

If you don't have enough electrons to satisfy the octet rule, you can add a multiple bond between atoms.
