Chemical Bonding Review

Front

What type of bond is formed between magnesium (Mg) and oxygen (O)?

Back

Ionic bond.

Front

What is a chemical bond that involves the sharing of electrons between nonmetals called?

Back

Covalent bond.

Front

What causes an ion to have a charge?

Back

An ion has a charge due to a different number of protons and electrons.

Front

Where are valence electrons found in an atom?

Back

In the outer-most shell of an atom.

Front

What best describes valence electrons?

Back

Electrons in the outer-most shell.

Front

What is the primary characteristic of ionic bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another.

Front

What type of bond is typically formed between two nonmetals?

Back

Covalent bond.

Front

What is the octet rule in relation to chemical bonding?

Back

Atoms tend to bond in a way that gives them eight valence electrons.

Front

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond has unequal sharing of electrons, while a nonpolar covalent bond has equal sharing.

Front

What is the role of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond.
