Goto: Build an Atom simulation (https://phet.colorado.edu/en/simulation/build-an-atom)
Click to RUN the "Build an Atom" simulation.
1. Click on the Atom. Play with subatomic particles until you discover which particle (s) determine the name of the element you build.
Which particle determine the name of the element?
a)proton
b)electron
c)neutron
Answer: What is the name of the following atoms?
a) An atom with 3 protons and 3 neutrons: _____________
b) An atom with 3 protons and 4 neutrons: _____________
c) An atom with 4 protons and 4 neutrons: _____________
2. Continue on the Atom. Play with the simulation to discover which particles affect the charge of an atom or ion.
Which particles affect the charge of an atom or ion?
Fill in the blanks below to show your results:
Neutral atoms have the same number of protons and electrons.
Positive ions have ________________________________ protons than electrons.
Negative ions have _______________________________ protons than electrons.
3. Now click on the symbol. Play with the atomic symbol of the atom and discover which subatomic particles affects the mass number of your atom or ion.
Which particles affect the mass number?
