3.7 Covalent Bonding

Front

What is a covalent bond?

Back

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

Front

What types of atoms typically form covalent bonds?

Back

Covalent bonds typically form between two non-metal atoms.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed from the transfer of electrons between a metal and a non-metal, while covalent compounds are formed by the sharing of electrons between non-metals.

Front

What is the formula for a covalent compound?

Back

Covalent compounds can be represented by molecular formulas, such as H2O (water) or CO2 (carbon dioxide).

Front

What is an example of a covalent compound?

Back

An example of a covalent compound is sulfur dioxide (SO2).

Front

How do you identify a covalent compound?

Back

Covalent compounds usually consist of two or more non-metals and have low melting and boiling points.

Front

What is the significance of electron sharing in covalent bonds?

Back

Electron sharing allows atoms to achieve a full outer shell, leading to greater stability.

Front

What is a molecular formula?

Back

A molecular formula shows the number and type of atoms in a molecule, such as C6H12O6 for glucose.

Front

What is a diatomic molecule?

Back

A diatomic molecule is a molecule composed of two atoms, which can be of the same or different elements, like O2 or HCl.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally, resulting in a molecule with a slight charge.
