phet lab build an atom simulation
google: phet lab build an atom
atoms are the smallest particle of an element that retain the properties of that element.
atoms are made of three subatomic particles; protons, neutrons, and electrons (p⁺, n⁰, e⁻).
protons have a mass of __ amu and a charge of __.
neutrons have a mass of __ amu and a charge of __.
electrons have a mass of nearly __ amu and a charge of __.

procedure: use the phet lab “build an atom” simulation.
check all 3 boxes in “show” (example left) and click all 3 green - boxes for element, net charge, and mass number.
become familiar with the simulation. notice what happens to the element, the charge, and the mass when you add p⁺, n⁰, or e⁻. to start over with a new atom, click
build the first 10 elements on the periodic table.
make sure you build an atom for each element that is stable (some element have more than 1 stable isotope, one stable isotope is fine) and has 0 net charge.

Explanation:

Protons have a mass of approximately 1 amu and a charge of +1. Neutrons have a mass of approximately 1 amu and a charge of 0. Electrons have a mass of nearly 0 amu and a charge of - 1. For the first 10 elements:

• Hydrogen (H): Atomic number 1, 1 proton, 0 neutrons, mass number 1, 1 electron.
• Helium (He): Atomic number 2, 2 protons, 2 neutrons, mass number 4, 2 electrons.
• Lithium (Li): Atomic number 3, 3 protons, 4 neutrons, mass number 7, 3 electrons.
• Beryllium (Be): Atomic number 4, 4 protons, 5 neutrons, mass number 9, 4 electrons.
• Boron (B): Atomic number 5, 5 protons, 6 neutrons, mass number 11, 5 electrons.
• Carbon (C): Atomic number 6, 6 protons, 6 neutrons, mass number 12, 6 electrons.
• Nitrogen (N): Atomic number 7, 7 protons, 7 neutrons, mass number 14, 7 electrons.
• Oxygen (O): Atomic number 8, 8 protons, 8 neutrons, mass number 16, 8 electrons.
• Fluorine (F): Atomic number 9, 9 protons, 10 neutrons, mass number 19, 9 electrons.
• Neon (Ne): Atomic number 10, 10 protons, 10 neutrons, mass number 20, 10 electrons.
