Today is: Tuesday, August 30th 8/30/2016 #twothingstuesday 1. 2. Name two things you are really enjoying right now. It can be personal or academic! Explain why you enjoy those two things. What are the three particles that make up an atom? Which two are in the nucleus? Agenda: ● Atoms Family (Subatomic Particles) Science News: Seriously, stop feeding wild animals. Last Class: http://safeshare.tv/x/ss57c5a273adaec ● Matter and The following answers DO NOT have to be complete sentences. Atoms :) Next Class: 3. Why shouldn’t we feed white bread to ducks? Name TWO ● Atomic Theory reasons! 4. Why shouldn’t we feed peanuts to monkeys? 5. If you ARE going to feed ducks, what should you feed them instead? Learning Target: ● I can classify and explain the structure of an atom. I can classify and explain the structure of an atom, element, compound, mixture, as well as, the organization of the periodic table and the modern atomic theory. 4 In addition to mastering level 3, I make in-depth inferences and applications that go beyond what was taught in class. 3 I am able to classify: • atoms, elements, compounds, mixtures • heterogeneous/homogeneous mixtures I am able to explain: • the organization of the periodic table (families, groups, periods, reactivity, and atomic number) • the modern atomic theory 2 I can define the following terms: • Atom • Element • Compound • Mixture • Heterogeneous mixture • Homogeneous mixture • Periodic Table • Family • Group • Period • Atomic theory • Proton • Neutron • Electron 1 With help, I can perform at level 2 Matter has mass and takes up space. Matter vs. Not Matter ANSWERS Electricity Sounds Music Clouds Paper Bacteria Wisdom Skin cells Heat A cat Wind Atoms The ocean Ketchup Smoke Liquid Gravity Force Fire Steam Helium DNA Light Love Water Dissolved sugar Thoughts Carbon Energy Moonlight Crystals Motion Feelings Ideas Hot Cheetos Mars Chapter K4 Section 2 The Atom Bellringer Answer the following question: An atom is the smallest particle into which an element can be divided and still be that element. Now that scientists have learned that an atom is made up of even smaller particles, is this definition still accurate? Explain your answer in your science journal.

Scientists know that aluminum is made of average-sized atoms. An aluminum atom has a diameter of about 0.00000003 cm. Chapter menu Resources Copyright © by Holt, Rinehart and Winston. All rights reserved. Chapter K4 Section 2 The Atom What Is an Atom Made Of? • The Nucleus Protons are positively charged particles in the nucleus. Neutrons are the particles of the nucleus that have no electrical charge. • Outside the Nucleus Electrons are the negatively charged particles in atoms. Electrons are found around the nucleus within electron clouds. All the structures of the atom can be seen on the next slide. Chapter menu Resources Copyright © by Holt, Rinehart and Winston.

Chapter K4 Section 2 The Atom How Do Atoms of Different Elements Differ? • Starting Simply The hydrogen atom has one proton and one electron. • Now for Some Neutrons The helium atom has two protons, two neutrons, and two electrons.

Chapter K4 Section 2 The Atom How Do Atoms of Different Elements Differ? • Building Bigger Atoms For bigger atoms, simply add protons, neutrons, and electrons. • Protons and Atomic Number The number of protons in the nucleus of an atom is the atomic number of that atom. All atoms of an element have the same atomic number. Chapter menu Resources Copyright © by Holt, Rinehart and Winston. All rights reserved.
