Atomic Mass
How do you find the number of neutrons in an element?
Neutrons = Atomic Mass - # of Protons
Neutrons = # of Protons - # of electrons
Neutrons = Atomic Number - Atomic Mass
Neutrons = # of electrons - Atomic Mass
What is the atomic Mass?
The mass of an element
Atoms that have the same number of protons but a different number of neutrons
Few electrons in outer energy level and a good conductor of thermal energy
Almost complete set of electrons in energy levels and a poor conductor of thermal energy
What is an isotope?
The mass of an element
Atoms that have the same number of protons but a different number of neutrons
Few electrons in outer energy level and a good conductor of thermal energy
Almost complete set of electrons in energy levels and a poor conductor of thermal energy
What is a Metal?
The mass of an element
Atoms that have the same number of protons but a different number of neutrons

Almost complete set of electrons in energy levels and a poor conductor of thermal energy
What is a nonmetal?
The mass of an element
Atoms that have the same number of protons but a different number of neutrons
Few electrons in outer energy level and a good conductor of thermal energy
Almost complete set of electrons in energy levels and a poor conductor of thermal energy
A substance that can’t be broken down into a simpler substance
