Homework: Quiz NEXT CLASS 9/14-15 (lab safety, sci method, chemistry) Warm Up 6: (Write the question & all answer choices) 1.The nucleus of an atom contains A.Only neutrons B. Protons and electrons C.Protons and neutrons D. Only electrons 2. List the 3 subatomic particles and their charges. Objective: SWBAT create a model of the atomic structure.

Remember…. The 3 subatomic particles are… Protons– have a positive charge Electrons– have a negative charge Neutrons– have no charge (neutral)

How to read the periodic table Open the yellow textbook to the periodic table.

How many protons and neutrons are in an atom of…. Helium Nitrogen Oxygen Phosphorous Gallium Atomic Number: # of protons in an atom Atomic Mass (Weight): Sum weight of protons and neutrons # protons + # neutrons = Atomic Mass

How to find the number of electrons? We want our atom to be neutral. Since protons have a positive charge, we need to cancel them out with a negative charge (electron). Because of this, we must have the same number of protons and electrons!

How many electrons are in an atom of…. Helium Nitrogen Oxygen Phosphorous Gallium

Atomic Models Atomic Models are used to represent the atomic structure of individual atoms. We will use the Bohr Model This model shows the reactivity of the element.

Bohr Model 1. How many protons, neutrons, and electrons does it have? 2. Draw a circle to represent the nucleus. 3. Use capital "P" to represent the protons inside the nucleus. 1 "P" = 1 proton 4. Use capital "N" to represent the neutrons insidethe nucleus. 1 "N" = 1 neutron Example: Oxygen P = 8 N = 8 E = 8 Oxygen P=8 N=8

Bohr Model cont. 5. Draw rings around the outside of the nucleus to represent the electron cloud. Electrons are represented by colored dots. REMEMBER not to put more than the maximum number of electrons that each level of the electron cloud can hold. Level one will hold 2 electrons Level two will hold 8 electrons Level three will hold 18 electrons Example: Oxygen P = 8 N = 8 E = 8 Oxygen P=8 N=8
