Chapter 2, Problem 2PIT
Summary Introduction
To explain:
The positions of ions and isotopes that can be fitted into this concept map.
Concept introduction:
Atom is the smallest unit of mater that cannot be broken down by chemical means. Atoms typically have one electron for each proton, so they are neutral that means it has no electrical charge.
