4

Front

What are valence electrons?

Back

Electrons farthest away from the nucleus.

Front

How do missing valence electrons affect an element's reactivity?

Back

If the valence shell has missing electrons, it is very reactive to attract or lose more electrons.

Front

What is the significance of the octet rule in chemistry?

Back

Atoms tend to be more stable when they have eight electrons in their valence shell.

Front

What is the relationship between valence electrons and chemical bonding?

Back

Valence electrons are involved in forming bonds between atoms.
