Ionic vs Covalent

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, resulting in charged ions. Covalent bonds involve the sharing of electrons between atoms.

Front

Define a cation.

Back

A cation is a positively charged ion, typically formed when a metal loses one or more electrons.

Front

Define an anion.

Back

An anion is a negatively charged ion, typically formed when a non-metal gains one or more electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full valence shell of eight electrons.

Front

What type of bond is formed between sodium (Na) and chlorine (Cl)?

Back

An ionic bond is formed between sodium and chlorine.

Front

What type of bond is formed in carbon dioxide (CO2)?

Back

A covalent bond is formed in carbon dioxide (CO2).

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be either covalent or ionic.

Front

Give an example of a covalent compound.

Back

Water (H2O) is an example of a covalent compound.

Front

What is electronegativity?

Back

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

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where electrons are shared unequally between atoms, resulting in partial charges.
