Covalent Bonds

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What does an electron dot diagram represent?

Back

An electron dot diagram represents the valence electrons of an atom and how they are shared or transferred in a bond.

Front

What does a double bond represent in an electron dot diagram?

Back

A double bond represents two pairs of shared electrons between two atoms.

Front

Can a molecule with polar bonds be nonpolar overall?

Back

Yes, a molecule with polar bonds can be nonpolar overall if the bond dipoles cancel each other out.

Front

What is the general boiling point of molecular compounds compared to ionic compounds?

Back

Molecular compounds generally have a lower boiling point than ionic compounds.

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

Front

True or False: A covalent bond is formed when two atoms share electrons.

Back

True.

Front

True or False: Covalent bonds usually form between a nonmetal and a metal.

Back

False.

Front

What is a polar bond?

Back

A polar bond is a type of covalent bond where electrons are shared unequally between two atoms, resulting in a dipole moment.

Front

What is the difference between a single bond and a triple bond?

Back

A single bond involves one pair of shared electrons, while a triple bond involves three pairs of shared electrons.
