Chem 1010 Notes Chase Bobier Week 5 Notes. Important terms Things you need to know Atoms, Isotopes, and the Periodic Table of the Elements. Isotopes Isotopes are varieties of one element with a different number of neutrons in the nucleus. This change in atomic mass causes them to act in a slightly different manner than the original version of the element. Atoms have a neutral charge (The number of protons and electrons is even) Cations have a positive charge (The number of protons is greater than the number of electrons) Anions have a negative charge (The number of electrons outweighs the number of protons.) Atomic mass is the weight of a specific atom or isotope. It will always be a whole number. Atomic Weight is the avera
