CP - U7 Covalent Practice

Front

What are covalent bonds?

Back

Covalent bonds are chemical bonds formed by the sharing of electrons between two non-metal atoms.

Front

What is the chemical formula for phosphorous trichloride?

Back

PCl₃

Front

How many valence electrons do most atoms need to be stable?

Back

Most atoms need 8 valence electrons to be stable, following the octet rule.

Front

How are covalent bonds formed?

Back

Covalent bonds are formed by the sharing of electrons between atoms.

Front

How many bonds does each nitrogen atom typically make?

Back

Each nitrogen atom typically makes 3 bonds.

Front

What is a non-metal?

Back

Non-metals are elements that are typically poor conductors of heat and electricity and can gain electrons easily.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell.

Front

What is a molecule?

Back

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

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 valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.
