ATOMIC STRUCTURE

Subatomic Particles Bohr Model A nucleus consisting of positively charged (protons) and neutral (neutrons) particles that are orbited by electrons in fixed energy levels. How small is an Atom? https://www.youtube.com/watch?feature=youtu.be&v=yQP4UJhNn0I&app=desktop Have You Ever Seen an Atom? https://m.youtube.com/watch?feature=youtu.be&v=yqLlgIaz1L0 A Boy And His Atom: The World's Smallest Movie https://m.youtube.com/watch?feature=youtu.be&v=oSCX78-8-q0

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

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 #

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

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

Subatomic Particles Isotope: Same element with a different number of neutrons [therefore, different Mass #]. https://www.youtube.com/watch?v=xjY5p-1CDr8

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

Subatomic Particles Mass Number: Atomic Mass: Protons + Neutrons Atomic Mass: Average Mass of all the isotopes based on their relative abundance. https://www.youtube.com/watch?v=aqfQKzbTCVo

Subatomic Particles Electron (e-) Negative (-) Charge 1/1836 AMU Are Fundamental Particles. Negative (-) Charge 1/1836 AMU  In an unreacted atom; # of Protons = # of e-
