8. Subatomic Particles Nucleus:
A nucleus consisting of positively charged (protons) and neutral (neutrons) particles.

9. Subatomic Particles
Proton – Comprised of Fundamental Particles called Quarks. [two up quarks and one down quark - uud]
Positive (+) Charge
One (1) AMU
# of Protons = Atomic #

10. Subatomic Particles
Quark – Fundamental particle that make up (in groups of three) Protons and Neutrons.

11. Subatomic Particles
Neutron - Comprised of Fundamental Particles called Quarks. [one up quark and two down quarks - udd]
No Charge (neutral)
One (1) AMU
# of Protons
+ # of Neutrons
Mass Number

12. Subatomic Particles Isotope: Same element with a different number of
neutrons [therefore, different Mass #].

13. Subatomic Particles Isotopes are denoted by their Mass Number:
Carbon-12 {six protons + six neutrons}
Carbon-14 {six protons + eight neutrons}

14. Subatomic Particles Mass Number: Atomic Mass:
Protons + Neutrons
Atomic Mass:
Average Mass of all the isotopes
based on their relative abundance.

15. Subatomic Particles Electron (e-) Negative (-) Charge 1/1836 AMU
Are Fundamental Particles.
Negative (-) Charge
1/1836 AMU
