the number of electrons equal to the number of protons
a low level of reactivity
A) What are valence electrons? (1 point)
the electrons in an atom’s outermost energy level
electrons that are exchanged between atoms
electrons that are shared between atoms
the electrons surrounding an atom’s nucleus
A) Why do atoms exchange or share electrons during bonding? (1 point)
to have eight inner level electrons
to obtain a full outer electron shell
to attract an ion with the opposite charge
to become neutral
