Lewis Dot Structure FA

Front

What is the molecular shape of BF3?

Back

Trigonal planar.

Front

What do nonmetals tend to do in terms of electron behavior?

Back

Gain electrons.

Front

What charge is associated with potassium (K) in an ionic bond formation?

Back

1+.

Front

What is the molecular shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the molecular shape of a molecule with three bonding pairs and one lone pair?

Back

Trigonal pyramidal.

Front

What is the significance of Lewis dot structures in chemistry?

Back

They represent the valence electrons of atoms and help visualize bonding.

Front

How do you determine the shape of a molecule using VSEPR theory?

Back

By considering the number of bonding pairs and lone pairs around the central atom.

Front

What is the electron configuration of a nonmetal?

Back

Nonmetals typically have high electronegativities and gain electrons to achieve a full valence shell.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is the shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent.
