Which atom does not obey the octet rule?

Back

Hydrogen (H) does not obey the octet rule.

Front

What is required for a covalent bond to form?

Back

A covalent bond can form when an atom has unpaired valence electrons.

Front

What is the name of S6O3?

Back

The name of S6O3 is hexasulfur trioxide.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.

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 are valence electrons?

Back

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

Front

What is the difference between paired and unpaired valence electrons?

Back

Paired valence electrons are two electrons occupying the same orbital, while unpaired valence electrons are single electrons in an orbital.

Front

What is the significance of unpaired valence electrons in bonding?

Back

Unpaired valence electrons are crucial for forming covalent bonds, as they can be shared with other atoms.

Front

What is the molecular geometry of PCl5?

Back

The molecular geometry of PCl5 is trigonal bipyramidal.
