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

Back

Trigonal planar

Front

How can you determine if a molecule is polar or non-polar?

Back

By examining the symmetry of the molecule and the electronegativity of the atoms involved.

Bent

Front

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

Back

Tetrahedral

Front

What is the difference between polar and non-polar molecules?

Back

Polar molecules have an uneven distribution of charge, while non-polar molecules have an even distribution.

Front

What determines the polarity of a bond between two elements?

Back

The difference in electronegativity between the elements.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Back

Linear

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs can affect the shape of the molecule and the angles between bonding pairs.
