Lewis Dot Structures - Ionic and Covalent

Front

What is the octet rule?

Back

The octet rule states that most elements need 8 valence electrons to achieve a stable electron configuration.

Front

What is a Lewis Dot Structure?

Back

A Lewis Dot Structure is a diagram that represents the valence electrons of an atom and how they are shared or transferred in chemical bonds.

Front

How do you determine the number of valence electrons for an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

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 the symbols of the two atoms.

Front

What happens to the valence electrons in an ionic bond?

Back

In an ionic bond, one atom loses electrons and becomes a positively charged ion, while the other atom gains those electrons and becomes a negatively charged ion.

Front

What is the significance of the total number of valence electrons in a Lewis structure?

Back

The total number of valence electrons determines how atoms bond and the overall structure of the molecule.

Front

How do you adjust the valence electron count for a negatively charged ion?

Back

For a negatively charged ion, you add the charge to the total number of valence electrons.

Front

What is the Lewis Dot Structure for O2?

Back

The Lewis Dot Structure for O2 shows two oxygen atoms sharing two pairs of electrons.

Front

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

Back

The correct Lewis Dot Structure for F2 shows two fluorine atoms sharing one pair of electrons.
