Molecules and Extended Structures

Front

What is an ion?

Back

An ion is an atom or group of atoms that has an electric charge.

Front

What is a polymer?

Back

A polymer is a large molecule made up of repeating subunits called monomers, which are always molecules.

Front

What type of bond forms between metals and nonmetals?

Back

Ionic bonds form between metals and nonmetals.

Front

Which elements are likely to form a covalent bond?

Back

Covalent bonds typically form between two non-metals.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

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 metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals.

Front

Give an example of a covalent compound.

Back

An example of a covalent compound is hydrogen chloride (HCl).

Front

What is a molecule?

Back

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

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving stability.
