Outside of nucleus. Thomson’s discovery. Mass = 9.11 x 10. -28. g. Charge = -1.76 x 10. 8. C (coulombs). Proton. +. ve. charged particle. Inside nucleus. Rutherford’s discovery. Textbook Pages 4-5. Lesson Objectives. Appreciate that there are various models to illustrate atomic structure. Know that early models of atomic structure predicted that atoms and ions with noble gas electron arrangements should be stable. Subatomic Particles. subatomic-lower (or smaller) than an atom. Protons-positive particles. Neutrons-neutral particles. Electrons-negative particles. Location of particles. Protons and neutrons are in the nucleus (core) of the atom.. 8.3 . D. Relate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content.. APEMAN. August 10, 2016. 1. st. . When given any number, there are rules that can be followed to determine how many digits within that number are “precision” digits, also known as Significant Figures.. Determining Sig Figs. Let’s look at the 5 rules of Sig Figs:. of an Atom. Atoms. We know that most of the atom is actually . empty space filled with quickly moving electrons. .. The positive nucleus is so small it actually only takes up a tiny fraction of the size of the atom. Ironically, almost all of the atom’s mass is concentrated in this nucleus, which contains . The lab technician shown here is using a magnifying lens to examine a bacterial culture in a petri dish. When scientists cannot see the details of what they study, they try to obtain experimental data that help fill in the picture.. How and why has the Atomic Theory changed over time? . How can we describe the molecular motion of the states of matter? . Objectives. Students will explain that atoms are the smallest unit of an element and are composed of subatomic particles.. How and why has the Atomic Theory changed over time? . How can we describe the molecular motion of the states of matter? . Objectives. Students will explain that atoms are the smallest unit of an element and are composed of subatomic particles.. Over the past century scientist have discovered that the atom is composed of 3 subatomic particles:. Protons. Neutrons. Electrons. Checking for understanding. Draw this diagram. Label all subatomic particles and include their charges.. Which particles make up the mass?. How many electrons can go on each shell?. Date:. YEAR 10 CHEMISTRY SESSION. Monday, 29 June 2020. Name the 3 subatomic particles?. Protons, electrons and neutrons. Which particles make up the mass?.
