Covalent Bonds

Front

What is a double bond in terms of electron sharing?

Back

A double bond is a chemical bond where two pairs of electrons are shared between two atoms.

Front

What type of bond is formed when two atoms share electrons?

Back

A covalent bond.

Front

True or False: Covalent bonds usually form when a nonmetal combines with a metal.

Back

False, covalent bonds typically form between nonmetals.

Front

What characterizes a polar covalent bond?

Back

In a polar covalent bond, one atom has a greater electronegativity and pulls on the shared electrons more than the other atom.

Front

True or False: An ion is a neutral group of atoms joined by covalent bonds.

Back

False, an ion is a charged particle, while a neutral group of atoms joined by covalent bonds is called a molecule.

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

What is electronegativity?

Back

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

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is the significance of electron dot diagrams?

Back

Electron dot diagrams visually represent the valence electrons of atoms and how they are shared or transferred in bonds.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where electrons are shared equally between two atoms.
