How are electrons configured in atoms? What are subatomic particles? How do we determine the number of Subatomic Particles in an atom? The parts that make up an atom. ◦ PEN: Protons, Electron, Neutrons Atomic Number= # of protons & electrons (in a neutral atom) Atomic Mass= #protons + # neutrons Mass # Protons What is the Bohr Model? 1 1 Bohr’s Model was used to explain the energy of atoms Only works for Hydrogen, but is good visualization for atomic structure P+ : 1 E-: 1 N0:1-1= 0 nucleus 1p+ e Electron Energy Shell + - How do we make a Bohr Model? 1. 2. Determine # protons & Neutron draw them in inner circle Determine # Electrons place in energy levels as follows 1st energy level= 2e- max 2nd energy level= 8e- max 3rd energy level= 18e- max LET’S PRACTICE WITH NITROGEN! Nitrogen-14 1. Determine # protons & Neutron draw them in inner circle 2. Determine # Electrons place in energy levels as follows 1st energy level= 2e- max 2nd energy level= 8e- max 3rd energy level= 18e- max P+ EN0 What are Valence Electrons? What’s the Octet Rule? Electrons in the outer most shell ◦ Determine elements chemical properties Atoms gain, lose, or share electrons in order to have 8 valence electrons How do valence electrons effect an elements reactivity?
