Bonding Exam Practice Review

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed by the sharing of valence electrons between two nonmetal atoms.

Front

What are cations?

Back

Cations are positively charged ions that are formed when an atom loses one or more electrons.

Front

What types of atoms form ionic bonds?

Back

Ionic bonds occur between metals and nonmetals.

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

What is the chemical formula for Beryllium iodide?

Back

The chemical formula for Beryllium iodide is BeI2.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

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.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between two atoms, resulting in a partial positive and negative charge.
