ATOMIC PHYSICS The nuclear atom All matter is made up of atoms which consist of a central nucleus‚ surrounded by electrons. Inside the nucleus are protons and neutrons. Particle Relative mass Charge Location Proton 1840 + Nucleus Neutron 1840 0 Nucleus Electron 1 - Outside nucleus Proton or atomic number (Z) This is the total number of protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon

1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame 2. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did. Part Two (Spectroscopy): 1. Create and complete a data table for Part Two of the lab. It should include the name of the element‚ the colors‚ and the wavelength values of the observed lines. 2. Describe the line spectrum

This is not very accurate data because there is air in the room too. And the doll on the parachute is always moving around when it drop‚ so the distance of the parachute is not very accurate. Conclusion: In this lab‚ we have changed our IV and DV after we done the first time lab because we can’t measure the air

Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change
