The three classes of elements are these.
What are metals, metalloids, and nonmetals?
The atomic number tells you
What is the number of protons (and electrons) an atom of an element has?
An atom that has extra nuetrons in its nucleus is called
an isotope
The location of protons and neutrons.
What is inside the nucleus?

What are metalloids?
What is a atom that has charge or is not neutral
an ion
The location of electrons.
