08 Covalent Bonding

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What are the characteristics of covalent compounds?

Back

Covalent compounds typically have lower melting and boiling points than ionic compounds, are often gases or liquids at room temperature, and do not conduct electricity.

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, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged entity composed of two or more atoms bonded together, which can act as a single unit in chemical reactions.

Front

How do you name covalent compounds?

Back

Covalent compounds are named using prefixes to indicate the number of atoms of each element present, followed by the name of the first element and the root of the second element with an '-ide' suffix.

Front

What is the chemical formula for water?

Back

The chemical formula for water is H₂O.

Front

What is the significance of the 'octet rule' in covalent bonding?

Back

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

Front

What is a molecular compound?

Back

A molecular compound is a compound formed by the covalent bonding of two or more nonmetals.

Front

What is the chemical formula for carbon dioxide?

Back

The chemical formula for carbon dioxide is CO₂.

Front

What are diatomic molecules?

Back

Diatomic molecules are molecules composed of only two atoms, which can be of the same or different chemical elements.
