Explanation & Answer
Hey there! Here's the completed worksheet. Let me know if you have any questions! Thank you so much! 😀
BUILD AN ATOM
PART I: ATOM SCREEN
Build an Atom simulation (http://phet.colorado.edu/en/simulation/build-an-atom)
1.
2.
Explore the Build an Atom simulation with your group. As you explore, talk about what you
find.
a) List two things your group observed in the simulation.
For a given combination of protons, neutrons, and electrons, a certain element will be built.
The electrons are located in the orbits while the protons and neutrons are located in the
center or the nucleus
b) What particle(s) are found in the center of the atom?
The nucleus is comprised of the proton and the neutron.
3.
Play until you discover which particle(s) determine(s) the name of the element you build.
What did you discover?
The number of protons dictates which element is built.
4.
What is the name of the following atoms?
a) An atom with 3 protons and 4 neutrons: Lithium
b) An atom with 2 protons and 4 neutrons: Helium
c) An atom with 4 protons and 4 neutrons: Beryllium
5.
Play with the simulation to discover which particles affect the charge of an atom or ion.
a) Fill in the blanks below to show your results:
Neutral atoms have the same number of protons and electrons.
Positive ions have more protons than electrons.
Negative ions have less protons than electrons.
b) Develop a relationship (in the form of a single sentence or equation) that can predict the
charge based on the number and types of particle.
Charge of particle = No. of protons – No. of elect...
