Valence
How does an element become an ion?
By gaining/losing electrons
The definition of an isotope.
An element with the same number of Protons/Electrons, but a different number of Neutrons
Which element has a symbol that starts with a letter different from the first one in its name: aluminum, copper, gold, rhenium?
Gold
Most of the electron cloud is made of this
