What is the significance of valence electrons in chemical bonding?

Back

Valence electrons are important because they are involved in forming bonds with other atoms.

Front

What is the maximum number of electrons that can occupy the outer shell of an atom?

Back

The maximum number of electrons that can occupy the outer shell of an atom is 8, according to the octet rule.

Front

What does the term 'octet rule' refer to?

Back

The octet rule refers to the tendency of atoms to prefer to have eight electrons in their valence shell.

Front

How do you determine the number of valence electrons for an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.
