Knowledge Check- Covalent Bonds

Front

What is a covalent bond?

Back

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

Front

What determines the number of bonds an element will form in a covalent compound?

Back

The number of electrons needed to reach an octet.

Front

What does an electron dot diagram represent?

Back

An electron dot diagram (or Lewis dot structure) is a model of an atom in which each dot represents a valence electron.

Front

How can you identify if a compound is ionic or covalent?

Back

Ionic compounds typically form between metals and nonmetals, while covalent compounds form between nonmetals.

Front

What is the octet rule?

Back

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

Front

Which element typically forms three covalent bonds?

Back

Phosphorous.

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 is a Lewis structure?

Back

A Lewis structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What type of bond is formed in the compound SO2?

Back

Covalent bond.

Front

What is the significance of valence electrons in covalent bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom and are involved in forming bonds with other atoms.
